BASE CHANGE FOR BERNSTEIN CENTERS OF DEPTH ZERO PRINCIPAL SERIES BLOCKS
BERNSTEIN ZERO PRINCIPAL SERIES BLOCKS
2015/9/29
Let G be an unrami ed group over a p-adic eld. This article introduces a base change homomorphism for Bernstein centers of depth-zero principal
series blocks for G and proves the corresponding base ...
A New Preconditioner with Two Variable Relaxation Parameters for Saddle Point Linear Systems with Highly Singular(1,1) Blocks
Saddle Point Linear Systems Block Triangular Preconditioner Krylov Subspace Methods
2013/1/30
In this paper, we provide new preconditioner for saddle point linear systems with (1,1) blocks that have a high nullity. The preconditioner is block triangular diagonal with two variable relaxation pa...
Jackknife and bootstrap with cycling blocks for the estimation of fractional parameter in ARFIMA model
Jackknife bootstrap fractionally parameter ARFIMA model moving blocks non overlapping blocks
2011/4/6
One of most important problems concerning the ARFIMA time series model is the estimation of fractional parameter d. Various methods have been used to solve this problem, such as the log-periodogram r...
Conjectures of Alperin and Broue for 2-blocks with elementary abelian defect groups of order 8
Conjectures of Alperin Broue for 2-blocks elementary abelian defect groups of order 8
2011/2/21
Using the classification of finite simple groups, we prove Alperin’s weight conjecture
and the character theoretic version of Brou´e’s abelian defect conjecture for 2-blocks of finite groups wi...
We prove that the Chow quotient parametrizing configurations of n points in Pd which generically lie on a rational normal curve is isomorphic to M0,n, generalizing the well-known d = 1 result of Kapra...
On blocks stably equivalent to a quantum complete intersection of dimension 9 in characteristic 3 and a case of the abelian defect group conjecture
On blocks stably equivalent to a quantum complete intersection of dimension 9 characteristic abelian defect group conjecture
2011/1/17
Using a stable equivalence due to Rouquier, we prove that Brou´e’s abelian defect group conjecture holds for 3-blocks of defect 2 whose Brauer correspondent has a unique isomorphism class of sim...

Universal deformation rings dihedral defect groups special biserial algebras
2011/1/19
Let k be an algebraically closed field of characteristic 2, and let W be the ring of infinite Witt vectors over k. Suppose G is a finite group and B is a block of kG with a dihedral
defect group D su...
We study instanton partition functions for N = 2 superconformal Sp(1) and SO(4) gauge theories. We find that they agree with the corresponding U(2) instanton partitions functions only after a non-triv...
Base change for Bernstein centers of depth zero principal series blocks
Base change Bernstein centers depth zero principal series blocks
2011/2/25
Let G be an unramified group over a p-adic field. This article intro-duces a base change homomorphism for Bernstein centers of depth-zero principal series blocks for G and proves the corresponding bas...
2-Blocks with minimal nonabelian defect groups
blocks of finite groups minimal nonabelian defect groups Alperin’s conjecture Dade’s conjecture
2011/1/19
We study numerical invariants of 2-blocks with minimal nonabelian defect groups. These groups were classified by Rédei (see [41]). If the defect group is also metacyclic, then the block invariants are...
On a conjecture of G. Malle and G. Navarro on nilpotent blocks
conjecture G. Malle G. Navarro nilpotent blocks
2010/11/18
In a recent article, G. Malle and G. Navarro conjectured that the $p$-blocks of a finite group all of whose height 0 characters have the same degree are exactly the nilpotent blocks defined by M. Bro...
Random modification effect in the size of the fluctuation of the LCS of two sequences of i.i.d. blocks
the LCS two sequences
2010/11/18
The problem of the order of the fluctuation of the Longest Common Subsequence (LCS) of two independent sequences has been open for decades. There exist contradicting conjectures on the topic, due to ...

moduli space vector bundles conformal eld theory
2010/12/10
We study a family of semiample divisors on the moduli spaceM0;n that come from the
theory of conformal blocks for the Lie algebra sln and level 1. The divisors we study are invariant under the action...

Channel Coding Multiple Coherence Blocks Queueing Constraints
2010/12/15
This paper investigates the performance of wireless systems that employ finite-blocklength channel codes for transmission and operate under queueing constraints in the form of limitations on buffer ov...

Blocks restricted rational Cherednik algebras
2010/12/8
We study the Dunkl-Opdam subalgebra of the rational Cherednik algebra for wreath products at t = 0, and use this to describe the block decomposition of restricted rational Cherednik
