Polynomial approach for the most general linear Fredholm integrodifferential-difference equations using Taylor matrix method

International Journal of Mathematics and Mathematical Sciences, 2006
A Taylor matrix method is developed to find an approximate solution of the most general linear Fredholm integrodifferential-difference equations with variable coefficients under the mixed conditions in terms of Taylor polynomials.

Privacy Protection by Matrix Transformation

IEICE Transactions on Information and Systems, 2009
Privacy preserving is indispensable in data mining. In this paper, we present a novel clustering method for distributed multi-party data sets using orthogonal transformation and data randomization techniques. Our method can not only protect privacy in face of collusion, but also achieve a higher level of accuracy compared to the existing methods.

A STUDY ON THE STRUCTURE OF MATRICES RELATED TO THE VECH*, VECP*, AND VEC OPERATORS

Barekeng
The vec operator is an essential tool in matrix algebra that transforms a matrix into a column vector based on specific rules. This paper introduces two new operators, namely  and , which take the main diagonal and supra-diagonal elements of the matrix ...

Generalized Laplace transform with matrix variables

International Journal of Mathematics and Mathematical Sciences, 1987
In the present paper we have extended generalized Laplace transforms of Joshi to the space of m×m symmetric matrices using the confluent hypergeometric function of matrix argument defined by Herz as kernel.

Stable matrices, the Cayley transform, and convergent matrices

International Journal of Mathematics and Mathematical Sciences, 1991
The main result is that a square matrix D is convergent (limn→∞Dn=0) if and only if it is the Cayley transform CA=(I−A)−1(I+A) of a stable matrix A, where a stable matrix is one whose characteristic values all have negative real parts.
