From Jantzen to Andersen Filtration via Tilting Equivalence
Jantzen Andersen Filtration via Tilting Equivalence
2010/11/12
The space of homomorphisms from a projective object to a Verma module in category O inherits an induced filtration from the Jantzen filtration on the Verma module. On the other hand there is the Ande...
Equivalence of domains for hyperbolic Hubbard-Stratonovich transformations

We settle a long standing issue concerning the traditional derivation of non-compact non-linear sigma models in the theory of disordered electron systems: the hyperbolic Hubbard-Stratonovich (HS) tran...
We prove that existence of a k-rational point can be detected by the stable A^1-homotopy category of S^1-spectra
An asymptotic equivalence between two frame perturbation theorems
asymptotic equivalence two frame perturbation theorems

In this paper, two stability results regarding exponential frames are compared.The theorems, (one proven herein, and the other in [3]), each give a constant such that if supn∈Z kenk¥ < C, and (eih...
We demonstrate that the question whether or not a given topological ramified covering map of the 2-sphere is Thurston equivalent to a rational map is algorithmically decidable.
On the Equivalence of Weyl and Generalized Weyl Theorem
$B$-Fredholm operator Weyl's theorem generalized Weyl's theorem $a$-Weyl's theorem generalized $a$-Weyl's theorem poles

We know that an operator $T$ acting on a Banach space satisfying generalized Weyl's theorem also satisfies Weyl's theorem. Conversely we show that if all isolated eigenvalues of $T$ are poles of its r...
BFV-BRST analysis of equivalence between noncommutative and ordinary gauge theories
BFV-BRST analysis equivalence noncommutative ordinary gauge theories
2010/11/2
Constrained hamiltonian structure of noncommutative gauge theory for the gauge group U(1) is discussed. Constraints are shown to be first class, although, they do not give an Abelian algebra in terms...
