**MATH-100 Precalculus**

**MATH-100QR Precalculus: 'Problem Solving and Quantitative Reasoning'**

*Fall. **Credits: 4*

This course is intended for students who, based on the results of their mathematics assessment and the agreement of the instructor, need to strengthen their quantitative and algebraic skills in order to be ready to progress to further mathematics, science, and economics courses. In this class students learn to translate real problems into mathematics, to solve complex multi-step problems, and to gain confidence in using logarithms, exponents, and trigonometry in different contexts.

**MATH-114 Explorations in Number Theory**

*Spring. **Credits: 4*

We will cover the arithmetic of whole numbers and of prime numbers, in particular, examining some of the earliest questions in mathematics from a modern perspective, finding whole number solutions to equations with several variables, deciding whether or not such solutions exist and if so, determining whether the solution set is finite or infinite. Topics include the theory of 'finite arithmetic,' converting questions about the infinite set of whole numbers to those involving just a small set of primes, using computers to examine problems numerically.

**MATH-158MM Developing Mathematical Ideas: Making Meaning for Operations**

*Not Scheduled for This Year. **Credits: 2*

This course provides opportunities for participants to examine the actions and situations modeled by the four basic operations. The course will begin with a view of young children's counting strategies as they encounter word problems, moves to an examination of the four basic operations on whole numbers, and revisits the operations in the context of rational numbers.

**MATH-312 Abstract Algebra**

**MATH-312GT Abstract Algebra: 'Groups'**

*Spring. **Credits: 4*

Abstract algebra is the study of the common principles that govern computations with seemingly disparate objects. One way to begin is by studying groups, which are sets with a single operation under which each non-identity element is invertible. Examples include the integers with addition, invertible matrices of size n, permutations of a fixed set, and the symmetries of an object. Our goal is to study a definition of groups that unifies all of the important examples above and more.

**MATH-312RT Abstract Algebra: 'Rings'**

*Fall. **Credits: 4*

Abstract algebra is the study of the common principles that govern computations with seemingly disparate objects. One way to begin is by studying rings, which are sets with two operations, typically addition and multiplication. Examples include the integers, the integers modulo n, and polynomials in n variables. Our goal is to study a definition of rings that unifies all of the important examples above and more.

**MATH-319 Topics in Algebra**

**MATH-319CT Topics in Algebra: 'Combinatorics'**

*Fall. **Credits: 4*

This course is an investigation into the art of counting and combinatorial proof. Many mathematical formulas can be interpreted as counting some collection of objects with a particular structure. This allows us to apply simple counting arguments, and often we obtain beautiful and concrete proofs. Topics may include Fibonacci identities, Stirling numbers, inclusion-exclusion, continued fractions, and generating functions.

*Applies to requirement(s): Math Sciences**J. Tirrell**Prereq: MATH-232. *

**MATH-329 Topics in Geometry**

**MATH-329TP Topics in Geometry and Topology: 'Topology'**

*Spring. **Credits: 4*

This course is an introduction to point-set topology, which is a fundamental language for much of modern mathematics. One of the goals of topology is to understand what it means for a function to be continuous, first in Euclidean space, and then to generalize the notion of continuity to other spaces. The core topics to be studied include: basic set theory, various interesting topologies, continuous functions, connectedness and compactness. Topics from algebraic topology will be covered if time permits.

*Applies to requirement(s): Math Sciences**N. Gray**Prereq: MATH-232 and any 300-level math class. *

**MATH-333 Differential Equations**

*Fall and Spring. **Credits: 4*

**MATH-339 Topics in Applied Mathematics**

**MATH-339SP Topics in Applied Mathematics: 'Stochastic Processes'**

*Spring. **Credits: 4*

A stochastic process is a collection of random variables. For example, the daily prices of a particular stock are a stochastic process. Topics of this course will include Markov chains, queueing theory, the Poisson process, and Brownian motion. In addition to theory, the course will investigate applications of stochastic processes, including models of call centers and models of stock prices. Simulations of stochastic processes will also be used to compare with the theory.

**MATH-342 Probability**

*Fall and Spring. **Credits: 4*

This course develops the ideas of probability simultaneously from experimental and theoretical perspectives. The laboratory provides a range of experiences that enhance and sharpen the theoretical approach and, moreover, allows us to observe regularities in complex phenomena and to conjecture theorems. Topics include: introductory experiments; axiomatic probability; random variables, expectation, and variance; discrete distributions; continuous distributions; stochastic processes; functions of random variables; estimation and hypothesis testing.
