Birational Calabi--Yau n-folds have equal Betti numbers
Batyrev, Victor V.
Original · EN
Let X and Y be two smooth projective n-dimensional algebraic varieties X and Y over C with trivial canonical line bundles. We use methods of p-adic analysis on algebraic varieties over local number fields to prove that if X and Y are birational, they have the same Betti numbers.
