Math 4780 Introduction to Concurrency (3)

Prerequisites: Math 2170 and Math 3100 or approval of instructor.

This course is a general introduction to Concurrency, i.e., the Mathematical modeling of systems made up of several processes interacting with each other. The process algebra CSP (Communicating Sequential Processes) will be studied, both on the syntactic and semantic level. The denotational, operational, and algebraic models used to reason about the language will be presented, and examples will be used throughout to illustrate the theory.

Math 4900 (3)

Prerequisite: Permission of the Instructor.

This course covers a variety of advances in topics in mathematics and exposes students to recent developments not available in other parts of the mathematics curriculum. It meets ini conjunction with graduate level courses MATH 7710-7790 Topics covered will vary from semester to semester. Recent topics offered include Knot Theory and 3-Manifolds, Algebraic Combinatorics, Cardiac Modeling, Number Theory. Students may receive credit for MATH 490 more than once, when the topics covered are distinct. Each section will have the specific topic listed as a subtitle and will have specific prerequisites to the 300 level or above.
