Zero Sets of Polynomials in Several Variables
Let k, n ∈ IN, where n is odd. We show that there is an integer N = N(k, n) such that for every n-homogeneous polynomial P : IRN → IR there exists a linear subspace X ↪→ IRN , dimX = k such that P |X ≡ 0. This quantitative estimate improves on previous work of Birch, et al, who studied this problem from an algebraic viewpoint. The topological method of proof presented here also allows us to obt...
متن کاملRuscheweyh Differential Operator Sets of Basic Sets of Polynomials of Several Complex Variables in Hyperelliptical Regions
The idea of the basic sets of polynomials of one complex variable appeared in 1930’s by Whittaker [33,34,35] who laid down the definition of a basic sets and their effectiveness. The study of the basic sets of polynomials of several complex variables was initiated by Mursi and Makar [25,26], Nassif [27], Kishka and others [13,14,17,18,19], where the representation in polycylindrical and hypersp...

Some inequalities in connection to relative orders of entire functions of several complex variables
Let f, g and h be all entire functions of several complex variables. In this paper we would like to establish some inequalities on the basis of relative order and relative lower order of f with respect to g when the relative orders and relative lower orders of both f and g with respect to h are given.
متن کاملMonomial orthogonal polynomials of several variables
A monomial orthogonal polynomial of several variables is of the form x−Qα(x) for a multiindex α ∈ N 0 and it has the least L2 norm among all polynomials of the form xα − P (x), where P and Qα are polynomials of degree less than the total degree of xα. We study monomial orthogonal polynomials with respect to the weight function ∏d+1 i=1 |xi| 2κi on the unit sphere Sd as well as for the related w...
