Kronecker-weber plus Epsilon
We say that a group is almost abelian if every commutator is central and squares to the identity. Now let G be the Galois group of the algebraic closure of the field Q of rational numbers in the field C of complex numbers. Let Gab+ be the quotient of G universal for continuous homomorphisms to almost abelian profinite groups, and let Qab+ /Q be the corresponding Galois extension. We prove that ...

In this note we give a new proof of the theorem of Kronecker-Weber based on Kummer theory and Stickelberger’s theorem.
متن کاملFaltings plus Epsilon, Wiles plus Epsilon, and the Generalized Fermat Equation
Wiles’ proof of Fermat’s Last Theorem puts to rest one of the most famous unsolved problems in mathematics, a question that has been a wellspring for much of modern algebraic number theory. While celebrating Wiles’ achievement, one also feels a twinge of regret at Fermat’s demise. Is the Holy Grail of number theorists to become a mere footnote in the history books? Hoping to keep some of the sp...
متن کاملKronecker product approximations for dense block Toeplitz-plus-Hankel matrices
In this paper, we consider the approximation of dense block Toeplitz-plus-Hankel matrices by sums of Kronecker products. We present an algorithm for efficiently computing the matrix approximation that requires the factorization of matrices of much smaller dimension than that of the original. The main results are described for block Toeplitz matrices with Toeplitz-plus-Hankel blocks (BTTHB), but...
متن کاملClosure Generation Based on Viewing Lambda as Epsilon Plus Compile
This paper describes a way of expressing expressions which produce closures in terms of expressions expressions containing only local and global variable references and calls to an interactive compiler that compiles expressions This point of view is an interesting way of describing the semantics of expressions and closure generation It also leads to an e cient closure implementation both in tim...
