2017-2018 Catalogue

The science of mathematics has fascinated scholars since the beginning of classical thought. The mathematics program seeks to foster in students the power of disciplined thought, an appreciation of the intrinsic beauty of mathematics, a sound understanding of mathematical concepts, and the mathematical tools required by many areas of study. As part of the general education program, all Wesleyan students must successfully complete one course from MAT 140, 150, 192, 205, or 206.

The student learning outcomes for a student majoring in mathematics are:
I. to develop an understanding of the differential and integral calculus, and their applications;
II. to have foundational knowledge of more advanced branches of mathematics such as linear algebra, differential equations, analysis, abstract algebra, and probability and statistics, and their applications;
III. to acquire knowledge of methods of mathematical proof; and
IV. to be able to use mathematical techniques to analyze and solve a variety of applied and theoretical problems.
Major Program: Mathematics
The mathematics major provides breadth and depth in the study of mathematics and encourages students to achieve a sound understanding of the various areas of mathematics. Students who major in mathematics have many options, including careers in industry, government, statistics, teaching, and graduate study in mathematics and engineering. Wesleyan mathematics majors have enjoyed success in these and other career options.

A student majoring in mathematics first encounters the basic ideas and methods of analysis, algebra, and geometry in the required courses of calculus, computer science, linear algebra, discrete mathematics, and physics, learning both theoretical and applied aspects of the material. She continues with courses from differential equations, abstract algebra, real analysis, and other areas, giving further breadth to her knowledge of mathematics. At the same time, she deepens her knowledge through a two-semester sequence in real analysis or abstract algebra. Finally, a capstone course based upon topics in complex variables helps her see how concepts from various branches of mathematics combine to form this cornerstone of advanced mathematics. A student begins her mathematics program at the level indicated by her background, interests, and preparation as determined by a placement examination and consultation with a member of the mathematics faculty. Internships and research are encouraged.

Major Requirements: Mathematics.
The mathematics major requires a total of 50 semester hours, including MAT 205, 206, 207, 208, 210, 230, 300, 311, 401, 405 or 419, and 415 (33 semester hours), three semester hours selected from MAT 312 or 402; eight hours of physics (PHY 121 and 122); and six hours of computer science (CSC 216 and 218.) Many students who major in mathematics begin with MAT 205 in the first semester.

A recommended sequence of courses for the student majoring in mathematics is shown below. There is some flexibility as to when the required physics sequence and the CSC courses are taken. It is advisable to take the following courses during the first two years: MAT 205, 206, 207, 208, 210, 230 or 300, and CSC 216 and 218.

Students planning to do graduate work in mathematics should take both of the sequences in real analysis and abstract algebra. Note that the sequences MAT 311, 312 and MAT 401, 402 are offered in alternate years, so such students should plan to take one of these sequences in the junior year and the other in the senior year.

Professional Development: Throughout her Wesleyan education each student is given opportunities to explore professional and career choices, and to develop and demonstrate the knowledge and skills essential for professional success. Each student will complete a PDE 400 Professional Development Experience and submit a PDE 401 Professional ePortfolio prior to graduation. To develop her understanding of how a liberal arts education enhances a student's preparation for careers and further professional growth, each student majoring in mathematics will complete an internship, or a research experience approved by the mathematics faculty.

Integrative Experience: Each student majoring in mathematics will complete a general education Integrative Experience by taking either MAT 405 or MAT 419. Both of these courses require a semester project that asks the student to make connections between her general education and the mathematics major, and to consult with a faculty member outside of mathematics on the project.

Minor Requirements: Mathematics. A minor in mathematics consists of 15 semester hours including MAT 230, 206, 210, and two other MAT courses beyond MAT 205 (not to include MAT 220) selected in consultation with the academic advisor and a member of the mathematics faculty.

Resources for Non-Majors. All Wesleyan students are welcomed and encouraged to include the study of mathematics in their coursework. The study of mathematics provides necessary skills and concepts essential in other areas of study, including natural sciences, social sciences, business, and education. The student is guided in her selection of the appropriate mathematics courses by the requirements of each discipline, her previous mathematics courses, a placement examination, and consultation with her academic advisor and a member of the mathematics faculty.

Undergraduate Research Opportunities. Independent research is a highly desirable component of the curriculum for mathematics majors. Faculty members welcome the opportunity to support and direct the research efforts of students enrolled in MAT 451, 452, and 499.

Applied Mathematical Science

Applied Mathematical Science a major program for students who are interested in mathematics, but whose interests lie primarily with the practical application of mathematics to problems in the physical sciences, life sciences, economics, engineering, and other fields, rather than in the formal areas of abstract mathematics. Applied mathematics seeks to apply existing mathematical methods across a range of practical problems, as well as to develop novel computational and predictive methods and models for specific real-world phenomena. The Applied Mathematical Science major prepares students for graduate work and careers in such diverse areas as physics, astrophysics, geology, climatology, atmospheric science, genomics, neuroscience, economics, finance, energy management, and the diverse applications of engineering. This major also specifically prepares students for admission to engineering programs under the 3-2 Dual-Degree in Engineering. (See Pre-professional programs.)

The 3-2 Dual-Degree Engineering program is a cooperative arrangement between Wesleyan and specific universities combining a Wesleyan bachelor of arts degree with a university bachelor of science degree in a nominally five-year program. Wesleyan currently has dual-degree arrangements with Mercer University, Georgia Institute of Technology, and Auburn University. Under the dual degree arrangement the student attends Wesleyan for three years and completes 90 semester hours including proficiency and general educational requirements. She will follow a closely-advised pre-engineering program of courses in mathematics and the physical sciences, and will have the option of completing a major course of study, such as Applied Mathematical Science. If the student meets the transfer entrance requirements for the cooperating university program, she then transfers to that university for approximately two years of prescribed engineering courses. At the end of this nominally five-year program, provided that the student has met both Wesleyan proficiency and general education requirements and the curricular requirements of the cooperating university, the student earns a separate baccalaureate degree from each school.

The student learning goals for students majoring in Applied Mathematical Science and/or completing the Wesleyan component of the Dual-Degree in Engineering program are:

I. to develop a sound understanding of calculus, linear algebra, and differential equations;
II. to successfully write computer programs that solve mathematical problems;
III. to build theoretical and methodological foundations in the central, quantitative, laboratory-based physical sciences;
IV. to learn to recognize phenomena that may be represented and modeled using computational, analytical, and predictive mathematical techniques; and
V. to be able to apply mathematical techniques to a diverse range of problems in the natural and social sciences.
