Title: What is hyperbolic geometry?
Speaker: Mahan Maharaj, School of Mathematics, TIFR Bombay
Abstract: We shall indicate a solution to a problem posed by Euclid: Prove or disprove the parallel postulate assuming only the first 4 axioms of Euclidean geometry. The solution leads to a new geometry called hyperbolic geometry. We shall only assume some familiarity with calculus.
