# Mathematics

The Department of Mathematics, part of the natural and mathematical sciences discipline in the Columbian College of Arts and Sciences, offers the bachelor of arts in mathematics and bachelor of science in mathematics degrees. The undergraduate mathematics major has three concentrations: pure, applied, and interdisciplinary. Each concentration is designed to give students a solid background in the theory and practice of modern mathematics. A minor in mathematics is also available to undergraduate students.

At the graduate level, the department offers the master of arts in mathematics, master of science in applied mathematics, and doctor of philosophy in the field of mathematics. Course offerings are complemented by a generous selection of research seminars and by the department colloquium series. Faculty expertise covers a wide range of research specialties, allowing students to choose from a rich array of potential dissertation areas.

In addition, graduate certificates in mathematics and in financial mathematics are offered for those who seek to strengthen their mathematical backgrounds in order to better position themselves in their careers or to prepare themselves for graduate work in quantitative disciplines.

- The 6000s are open to advanced undergraduate students with approval of the instructor and the dean or advising office

Note: MATH 1220 Calculus with Precalculus I and MATH 1221 Calculus with Precalculus II each cover one-half the material of MATH 1231 Single-Variable Calculus I. Because MATH 1221 Calculus with Precalculus II, MATH 1231 Single-Variable Calculus I, and MATH 1252 Calculus for the Social and Management Sciences are related in their subject matter, credit for only one of the three may be applied toward a degree. The placement exam is the only option for placing into Math 1051, 1220, 1231, or 1252. Students with appropriate backgrounds may be admitted to any other course in the department by permission of the instructor in lieu of the listed prerequisites.
