To further appreciate the fundamental significance of F*(G) we must introduce a basic concept. Definition: Let X be any subset of the group G. The set CGX=g∈G:gx=xgforallx∈Xis a subgroup of G called the centralizer in G of X. Definition: Let G be a group and N a normal subg...
Systems of linear equations and reduced matrix in a linear algebra course for economics studies. Didactics of Mathematics, 2012, Nr 9 (13), s. 43-54 The article presents two elements of the concept of a linear algebra lecture for economics studies. It attempts to demonstrate the significant ...
Since the non-empty solution set of the fuzzy relation equations is in general a non-convex set, conventional linear programming methods are not suitable for solving such problems. The concept of covering problem is applied to establish 0–1 integer programming problem equivalent to linear ...
in the second half of nineteenth Century, because if when work reached its culmination in.1888, Peano axiomatically defined finite or infinite dimensional vector space. Toeplitz will be the main theorem is generalized to arbitrary body linear algebra on the general vector space. The concept of ...
However, the adjoint operator will, generally speaking, then be on another space, so the concept of a self-adjoint operator cannot be carried over to the general case. Let H = L2(a, b) and let U be the integral operator defined in 2.6; that is, y = U x is to mean (12)y(s)...
In the fuzzy literature, researchers have applied the concept of Vec-operator and Kronecker product for solving arbitrary fuzzy matrix equations (FME). How... AA Elsaycd,N Ahmad,G Malkawi - 《International Journal of Fuzzy System Applications》 被引量: 0发表: 2022年 On the solution of fully...
This chapter describes iterative methods for approximately solving systems of linear equations. This discussion begins by presenting the concept of a sparse matrix, where it arises and how it might be represented in a computer. Next, sim... Hirsch,W Morris 被引量: 0发表: 2013年 ...
From a number of descriptions with the same physical variable concept, such as Y = f (X) and Y =/(F(X)), only one description can be physically correct. In mathematics, a function of a function can be presented as a single function. In physics, such transformation can be a cause of...
