Referential expressions are used to introduce and continue reference to entities with par ticular referential properties, but also with particular discourse properties. In this paper we investigate the referential and discourse properties of pemarked indefi nite direct objects in Romanian, which are an instance of Diff erential Object Marking (DOM). Pe -marking is generally obligatory for defi ...

The problem of nding the smallest eigenvalue and the corresponding eigenspace of a symmetric matrix is stated as a semide nite optimization problem. A straightforward application of nowadays more or less standard routines for the solution of semide nite problems yields a new algorithm for the smallest eigenvalue problem; the approach not only yields the smallest eigenvalue, but also a symmetric...

Rhoades and Sava¸s [6],[11] established necessary for inclusions of the absolute matrix summabilities under additional conditions. In this paper we determine or su¢ cient conditions some classes in…nite matrices, using get more general applied to all matrices.

Specially structured Linear Complementarity Problems (LCP's) and their solution by the criss{ cross method are examined in this paper. The criss{cross method is known to be nite for LCP's with positive semide nite bisymmetric matrices and with P{matrices. It is also a simple nite algorithm for oriented matroid programming problems. Recently Cottle, Pang and Venkateswaran identi ed the class of ...

Fowlkes et al recently introduced an approximation to the Normalized Cut NCut grouping algorithm based on random subsampling and the Nystr om extension As presented their method is restricted to the case where W the weighted adjacency matrix is positive de nite Although many common measures of image similarity i e kernels are positive de nite a popular example being Gaussian weighted distance t...

A primitive matrix is a square matrix M with nonnegative real entries such that the entries of M are all positive for some positive integer s. The smallest such s is called the primitivity index of M . Primitive matrices of normal type (namely: MM and MM have the same zero entries) occur naturally in studying the so called ”conjugacy-class covering number”and ”character covering number”of a …ni...

Hilbert's 17th problem concerns expressing polynomials on R as a sum of squares. It is well known that many positive polynomials are not sums of squares; see [R00] [deA preprt] for excellent surveys. In this paper we consider symmetric non-commutative polynomials and call one \matrix positive", if whenever matrices of any size are substituted for the variables in the polynomial the matrix value...

In this paper, a new nite-element formulation for the solution of electromechanical boundary value problems is presented. As opposed to the standard formulation that uses scalar electric potential as nodal variables, this new formulation implements a vector potential from which components of electric displacement are derived. For linear piezoelectric materials with positive de nite material mod...
