متن کاملSimultaneous solution of linear equations and inequalities in max-algebra
Let a⊕b = max(a, b) and a⊗b = a+b for a, b ∈ R. Max-algebra is an analogue of linear algebra developed on the pair of operations (⊕,⊗) extended to matrices and vectors. The system of equations A ⊗ x = b and inequalities C ⊗ x ≤ d have each been studied in the literature. We consider a problem consisting of these two systems and present necessary and sufficient conditions for its solvability. We...
متن کاملDuality in linear interval equations
In this paper we nd solution of linear interval equation in dual form based on the generalizedprocedure of interval extension which is called interval extended zero method.Moreover, proposed method has signicant advantage, is that it substantially decreasesthe excess width eect.
متن کاملEstimations in Partial Differential Equations DDC
A general principle for error estimation Is described which can be applied to different types of partial differential equations. Particular attention is paid to nonlinear problems. With a programmed procedure based on this estimation principle, error bounds are calculated for boundary value problems involving the differential equation -Au + f(x,y,u) = 0.
متن کاملApproximate solutions to large Stein matrix equations
In the present paper, we propose numerical methods for solving the Stein equation AXC − X − D = 0 where the matrix A is large and sparse. Such problems appear in discrete-time control problems, filtering and image restoration. We consider the case where the matrix D is of full rank and the case where D is factored as a product of two matrices. The proposed methods are Krylov subspace methods ba...
