Pure Maths Colloquium: Counting curves in algebraic geometry
8 February 2010 16:15 in CM 107
This talk will assume no prior knowledge of geometry (just holomorphic functions). One can try to study "complex manifolds" or "algebraic varieties" via invariants that "count the holomorphic curves in them". This talk will be about explaining the notions in inverted commas; there are at least 4 different ways to define the the last one.
