Abstract:
I will present coarse geometry ideas, specifically index theory and cohomology, from the viewpoint of modern mathematical physics.\\
Prerequisites: Basic concepts in functional analysis, differential geometry, algebraic topology, and quantum mechanics.\\
Topics(tentative):
Lecture 1: Fredholm index in Quantum mechanics\\
Lecture 2: Operator algebras for coarse geometry\\
Lecture 3: Coarse index of Dirac operators coupled to gauge fields\\
Lecture 4: Partitions, coarse and cyclic cohomology, and trace pairings\\
Lecture 5: Application to large-scale quantization and quantum Hall effect.\\
