Art Galleries, Fortresses, and Prison Yards: Illumination and Color
نویسنده
چکیده
An art gallery problem asks for the minimum number of guards needed to protect a given geometric object such as a polygon or polyhedron. We emphasize results obtained using coloring arguments graphs. We also introduce a new technique (same-sign graphs) that simplifies the proofs of several known theorems. – This talk is accessible for graduate students in all areas of math, as well as advanced undergraduates.
