# IST Algebraic Topology (2015) - Speakers and Syllabus

Overview: Basic focus in this workshop is a discussion of the topology of curves, surfaces, and to give an introduction to Algebraic Topology through a discussion of homotopy, fundamental group, covering spaces and simplicial homology. Main emphasis will be to explain concepts through examples.Below is a more descriptive information about the syllabus.

Syllabus
Theme 1: Definition of manifolds as submanifolds of Rn , and tie this up with the standard abstract definition by discussing a proof of ‘medium form’ of the Whitney embedding theorem for compact manifolds.
Theme 2: Proof of triangulation of closed surfaces, classification theorem for surfaces. Discuss orientability, and show that closed surfaces embedded in R3 are necessarily orientable.
Theme 3: A discussion of quotient topology, group actions, quotient spaces, projective plane and Klein bottle. Embeddings of projective plane and Klein bottle in R4 .
Theme 4: A discussion of homotopy, path homotopy, homotopy equivalence, fundamental groups, covering spaces. Discuss fundamental groups of sphere, projective plane, torus, Klein bottle and higher genus surfaces.
Theme 5: Simplicial homology, singular homology, homotopy invariance, equivalence of simplicial and singular homology, homology and fundamental group.
