Title: "Rat GPS" - Drawing Place Field Diagrams of Neural Codes Using Toric Ideals
Abstract: A rat has special neurons that encode its geographic location. These neurons are called place cells and each place cell points to a region in the space, called a place field. Neural codes are collections of the firing patterns of place cells. In this talk, we investigate how to algorithmically draw a place field diagram of a neural code, building on existing work studying neural codes, ideas developed in the field of information visualization, and the toric ideal of a neural code. This talk is based on joint work with Dr. Elizabeth Gross (San Jose State University) and Dr. Nora Youngs (Colby College) [see: arXiv:1607.00697]. Students of all backgrounds (esp. undergrads interested in math research) are welcome and encouraged to attend; no prior knowledge will be assumed for this talk.

Description:
Title: Insolvability of classical Greek problems
Abstract:
The three Greek problems of antiquity had been among the most famous unsolved mathematics problems in history. The angle trisection, doubling the cube, and squaring the circle problems had not been settled till the advent of abstract algebra and analysis in 19th century.
The talk will describe one of activities of the departmental SMaRT (Summer Mathematics Research Training) high school camp, in which the students are led to proving the insolvability of the first two of these problems.
