Abstract of the talk
In this talk, we will look at the possible geometries (shapes) that can be taken by 2 and 3 dimensional manifolds (spaces). For a long time people assumed that the earth was flat till it was shown that, while it may seem to be locally flat, it globally takes on the shape of a sphere. What are some other “nice” shapes that 2-dimensional spaces can take? Similar questions can be asked for “nice” shapes of our 3-dimensional universe. We will attempt to answer some of these questions and will conclude with an overview of the uniformization theorem for surfaces and Thurston-Perelman’s Geometrisation theorem for 3-dimensional spaces.
About the speaker
Dr Tejas Kalelkar did his PhD from the Indian Statistical Institute and then was a postdoctoral fellow at Washington University in St Louis for three years. He returned and joined IISER Pune as a faculty in 2013. His broad area of research is geometric topology, in particular he works on various aspects of 3-dimensional manifolds.
