Be a commutative ring,. Be a multiplicatively closed subset in the sense that. Then we consider the localization. We can construct a m. And denote the corresponding local ring by. Be a prime ideal of. Is mc We denote the corresponding local ring by. Be the set of all prime ideals of. Is defined that the closed subsets are exactly. A basis for the Zariski topology on. We see that each maximal ideal.

This post will be something about the distribution of eigenvalues of one dimensional discrete Schrodinger operators in absolutely continuous spectrum region. Namely, given a triple. Then these together generates a family of operators.
