Nonstationary Extrapolated Modulus Algorithms for the solution of the Linear Complementarity Problem
Hadjidimos, A.; Tzoumas, M. (2009)The Linear Complementarity Problem (LCP) has many applications as, e.g., in the solution of Linear and Convex Quadratic Programming, in Free Boundary Value problems of Fluid Mechanics, etc. In the present work we assume ... -
On Brauer-Ostrowski and Brualdi sets
Hadjidimos, A.; Tzoumas, M. (2014)For the localization of the spectrum of the eigenvalues of a complex square matrix, the classical Gersgorin Theorem was extended by Ostrowski who used the generalized geometric mean of the row and column sums of the matrix. ... -
ON ITERATIVE SOLUTION FOR LINEAR COMPLEMENTARITY PROBLEM WITH AN H+-MATRIX
Hadjidimos, A.; Lapidakis, M.; Tzoumas, M. (2012)The numerous applications of the linear complementarity problem (LCP) in, e.g., the solution of linear and convex quadratic programming, free boundary value problems of fluid mechanics, and moving boundary value problems ... -
On the optimal complex extrapolation of the complex Cayley transform
Hadjidimos, A.; Tzoumas, M. (2009)The Cayley transform, F := F(A) = (I + A)(-1) (I - A), with A epsilon C(n.n) and -1 is not an element of sigma (A), where sigma(.) denotes spectrum, and its extrapolated counterpart F (omega A), omega epsilon C\{0} and -1 ... -
On the Solution of the Linear Complementarity Problem by the Generalized Accelerated Overrelaxation Iterative Method
Hadjidimos, A.; Tzoumas, M. (2015)In the present work, we determine intervals of convergence for the various parameters involved for what is known as the generalized accelerated overrelaxation iterative method for the solution of the linear complementarity ... -
The principle of extrapolation and the Cayley Transform
Hadjidimos, A.; Tzoumas, M. (2008)The Cayley Transform, F := (I + A)(-1)(I - A), with A is an element of C-n,C-n and -1 is not an element of sigma (A), where sigma(.) denotes spectrum, is of significant theoretical importance and interest and has many ...
