متن کاملSome Results on the Field of Values of Matrix Polynomials
In this paper, the notions of pseudofield of values and joint pseudofield of values of matrix polynomials are introduced and some of their algebraic and geometrical properties are studied. Moreover, the relationship between the pseudofield of values of a matrix polynomial and the pseudofield of values of its companion linearization is stated, and then some properties of the augmented field of ...
متن کاملAcidizing Corrosion Inhibitors: A Review
Oil well are periodically acidized for enhancing oil flow. Inhibited hydrochloric acid is used during acidization to prevent corrosion of N80 or J55 steel. In the present work authors have surveyed literature on acidizing corrosion inhibitors and the salient features of research work carried out by the authors have also been highlighted.
متن کاملdeterminant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
