Undergraduate Mathematics Day at the University of Dayton (UMD) is an undergraduate mathematics conference that is held in November of odd numbered years. We celebrate undergraduate mathematics in all its forms: research, history, teaching, and learning. One purpose of UMD is to provide a platform for undergraduate students to experience the excitement of investigation in the world of mathematics. The conference allows an opportunity for students to present results; the Electronic Proceedings gives the student experience to formally write a research or expository article. The articles are refereed for correctness and style.

We appreciate your interest in UMD. We believe this is a meaningful part of the process to share your ideas with the mathematics community.
