Sieve methods in group theory I: Powers in Linear groups
Sieve Property-T Powers Linear groups Finite groups of Lie type
2011/9/14
Abstract: A general sieve method for groups is formulated. It enables one to "measure" subsets of a finitely generated group. As an application we show that if $\Gamma$ is a finitely generated non vir...

Combinatorial Methods Surface Subgroups Right-Angled Artin Groups
2011/2/23
We give a short proof of the following theorem of Sang-hyun Kim:if A() is a right-angled Artin group with de ning graph , then A() contains a hyperbolic surface subgroup ...
A posteriori error estimator based on gradient recovery by averaging for convection-diffusion-reaction problems approximated by discontinuous Galerkin methods
averaging convection-diffusion-reaction problems discontinuous Galerkin methods
2010/11/9
We consider some (anisotropic and piecewise constant) convection-diffusion-reaction problems in domains of R2, approximated by a discontinuous Galerkin method with polynomials of any degree. We propos...
Stability of interconnected impulsive systems with and without time-delays using Lyapunov methods
interconnected impulsive systems Lyapunov methods
2010/11/18
We consider large-scale networks of impulsive systems with and without time-delays and investigate such systems in view of input-to-state stability (ISS). We provide conditions on the size of the tim...

Sixth International Conference Matrix-Analytic Methods in Stochastic Models
2008/2/29
Following the success of five previous conferences held in Flint (1995), Winnipeg (1998), Leuven (2000), Adelaide (2002), and Pisa (2005), the sixth international conference on matrix-analytic methods...
ON THE CONVERGENCE OF THE RELAXATION METHODS FOR POSITIVE DEFINITELINEAR SYSTEMS
System of linear equations Relaxation method Convergence theory Positive definite matrix
2007/12/12
We establish the convergence theories of the symmetric relaxation
methods for the system of linear equations with symmetric positive
definite coefficient matrix, and more generally, those of the
un...
In this paper, we develop a one-parameter family of P-stable
sixth-order and eighth-order two-step methods with minimal phase-lag
errors for numerical integration of second order periodic initial va...
In this paper, we propose a class of new NCP functions and discuss their
properties.
By these function, we transfer the complementarity
problem into unconstrained optimization problem and study ...
UNCONSTRAINED METHODS FOR GENERALIZED NONLINEAR COMPLEMENTARITY AND VARIATIONAL INEQUALITY PROBLEMS
2007/12/11
In this paper, we construct unconstrained methods for the generalized
nonlinear complementarity problem and variational inequalities. Properties of the correspondent unconstrained optimization

MATRIX ANALYSIS TO ADDITIVE SCHWARZ METHODS
2007/12/11
Matrix analysis on additive Schwarz methods as preconditioners is given
in this paper. Both cases of with and without coarse mesh are
considered. It is pointed out that an advantage of matrix analys...
