Title: Tensor products and isospectral manifolds
"Isospectral manifolds" are simply different shapes which produce the
same sound when vibrating. These are the counterexamples to Mark Kac's
famous question "can one hear the shape of a drum?".
I will present a construction method of isospectral manifolds which is
based on the notion of G-sets tensoring, and which gives a surprising
corollary: almost every manifold has isospectral, non-isometric
The talk is intended for general audience - no prior knowledge is assumed.
You are cordially invited!
