Singular localization and intertwining functors for reductive Lie algebras in prime characteristic
Lie algebra semisimple algebra group Springer fiber localization module is fixed
2014/12/25
In [BMR] we observed that, on the level of derived categories, representations of the Lie algebra of a semisimple algebraic group over a field of finite characteristic with a given (generalized) {\em ...
The Optimal Hard Threshold for Singular Values is 4/sqrt(3)
Optimal Hard Threshold Singular Values 4/sqrt(3)
2013/6/14
We consider recovery of low-rank matrices from noisy data by hard thresholding of singular values, where singular values below a prescribed threshold \lambda are set to 0. We study the asymptotic MSE ...
A Random Matrix--Theoretic Approach to Handling Singular Covariance Estimates
Random Matrix--Theoretic Approach Handling Singular Covariance Estimates
2010/10/19
In many practical situations we would like to estimate the covariance matrix of a set of variables from an insufficient amount of data. More specifically, if we have a set of $N$ independent, identica...
Gaussian semiparametric estimation for random fields with singular spectrum
Discrete Fourier transforms random fields singular spectrum Whittle semiparametric estimates
2009/9/21
We analyze the asymptotic behaviour of the tapered
discrete Fourier transforms far random fields with singular spectrum.
The results are used to establish consistency and asymptotic normality
for s...
APPLICATION OF THE EXACT INVERSE OF THE TOEPLITZ MARTRIX WITH SINGULAR RATIONAL SYIVlB0L TO RANDOM WALKS
Toeplitz matrices rational singular symbol random walk on a finite interval
2009/9/18
In the paper we study the random walks zy=,Xi on
the interval [O, Nj c 2, where Xi are i.i.d. random variables with
characteristic function @ = (1 -cos 0) 1 f'I2 Here f is a rational function.

GENERALIZED SEPARATION THEOREMS FOR SINGULAR VALUES OF A MATRIX AND THEIR APPLICATIONS IN CANONICAL CORRELATION ANALYSIS
Canonical correlations conditional canonical correlations singular values.
2009/9/18
Rao (1979) established separation theorems for singular
values of a matrix and showed their applications in multivariate
analysis. In this paper, we provide generalized separation theorems for
sing...
Total singular value decomposition Robust SVD，regression and location-scale

2010/4/29
Singular Value Decomposition (SVD) is the basic body of many statistical algorithms
and few users question whether SVD is properly handling its job.
SVD aims at evaluating the decomposition that bes...
