چکیده

We generalize an example, due to Sylvester, and prove that any monomial of degree d in R[x0, x1], which is not a power of a variable, cannot be written as a linear combination of fewer than d powers of linear forms.

MONOMIALS AS SUMS OF k-POWERS OF FORMS

Motivated by recent results on the Waring problem for polynomial rings [FOS12] and representation of monomial as sum of powers of linear forms [CCG12], we consider the problem of presenting monomials of degree kd as sums of kth-powers of forms of degree d. We produce a general bound on the number of summands for any number of variables which we refine in the two variables case. We completely so...

Varieties of Simultaneous Sums of Powers for binary forms

The problem of simultaneous decomposition of binary forms as sums of powers of linear forms is studied. For generic forms the minimal number of linear forms needed is found and the space parametrizing all the possible decompositions is described. These results are applied to the study of rational curves.

On Fibonacci Polynomial Expressions for Sums of mth Powers, their implications for Faulhaber’s Formula and some Theorems of Fermat

Denote by Σnm the sum of the m-th powers of the first n positive integers 1m + 2m + . . .+ nm. Similarly let Σrnm be the r-fold sum of the m-th powers of the first n positive integers, defined such that Σn = nm, and then recursively by Σn = Σr1m+Σr2m+ . . .+Σrnm. During the early 17th-century, polynomial expressions for the sums Σrnm and their factorisation and polynomial basis representation p...

Power of a Determinant with Two Physical Applications

An expression for the kth power of an n×n determinant in n2 indeterminates (zij) is given as a sum of monomials. Two applications of this expression are given: the first is the Regge generating function for the Clebsch-Gordan coefficients of the unitary group SU (2), noting also the relation to the 3F2 hypergeometric series; the second is to the even powers of the Vandermonde determinant, or, e...

The Real Holomorphy Ring and Sums of Powers in Rational and Elliptic Function Fields over The Field of Real Numbers

This thesis is devoted to a study of real holomorphy rings in R(x) and elliptic function fields R(x)( √ f(x)), f is a monic polynomial of degree 3 with no multiple roots in C over R and sums of powers in R(x). The objects of study are real valuation rings, real holomorphy rings and real places in the rational function fields R(x) and then investigate their extension to elliptic function fields ...
