Abstract:The famous Rokhlin divisibility asserts that the signature of 4 dimensional smooth spin manifold is divisible by 16. In this talk, we will first recall several generalized and similar divisibility results and then report our recent results on mod 3 congruence about twisted signature of 24 dimensional string manifolds. This represents our joint work with Qingtao Chen.
