Geometry of biperiodic alternating links
Abhijit Champanerkar (CUNY)
Location: Hill 525
Date & time: Tuesday, 16 October 2018 at 3:40PM - 4:40PM
Abstract: In this talk we will study the hyperbolic geometry of alternating link complements in the thickened torus. We will give conditions which imply the hyperbolicity of alternating link complements in the thickened torus. We show that these complements admit a positively oriented, unimodular geometric ideal triangulation, and determine sharp upper and lower volume bounds. For links which arise from semi-regular Euclidean tilings, called semi-regular links, we explicitly determine the complete hyperbolic structure on their complements and will discuss nice consequences like determination of exact volumes, arithmeticity and commensurability for this class of links. We will also discuss the Volume Density Conjecture and examples.
