Product and Puzzle Formulae for GLn Belkale-Kumar Coefficients
The Belkale-Kumar product on H(G/P) is a degeneration of the usual cup product on the cohomology ring of a generalized flag manifold. In the case G = GLn, it was used by N. Ressayre to determine the regular faces of the Littlewood-Richardson cone. We show that forG/P a (d−1)-step flagmanifold, each Belkale-Kumar structure constant is a product of ( d 2 ) Littlewood-Richardson numbers, for which...
متن کاملBranching Schubert Calculus and the Belkale-kumar Product on Cohomology
In [3], Belkale and Kumar define a new product on the cohomology of flag varieties and use this new product to give an improved solution to the eigencone problem for complex reductive groups. In this paper, we give a generalization of the Belkale-Kumar product to the branching Schubert calculus setting. The study of Branching Schubert calculus attempts to understand the induced map on cohomolog...
متن کاملQuadrature formulae for Fourier coefficients
We consider quadrature formulas of high degree of precision for the computation of the Fourier coefficients in expansions of functions with respect to a system of orthogonal polynomials. In particular, we show the uniqueness of a multiple node formula for the Fourier-Tchebycheff coefficients given by Michhelli and Sharma and construct new Gaussian formulas for the Fourier coefficients of a func...
متن کاملFormulae for cross sections and rate coefficients
Robust, accurate and asymptotically exact cross section formulae for all direct and dissociative electron impact ionization channels of methane and hydrogen are presented. The parameter estimation employs Bayesian inference and allows for a consistent use of data from different experiments with possibly discordant calibrations. An efficient method for the calculation of rate coefficients and th...
متن کاملRecurrences and explicit formulae for the expansion and connection coefficients in series of the product of two classical discrete orthogonal polynomials
Suppose that for an arbitrary function $f(x,y)$ of two discrete variables, we have the formal expansions. [f(x,y)=sumlimits_{m,n=0}^{infty }a_{m,n},P_{m}(x)P_{n}(y),] $$ x^{m}P_{j}(x)=sumlimits_{n=0}^{2m}a_{m,,n}(j)P_{j+m-n}(x),$$ we find the coefficients $b_{i,j}^{(p,q,ell ,,r)}$ in the expansion $$ x^{ell }y^{r},nabla _{x}^{p}nabla _{y}^{q},f(x,y)=x^{ell }y^{r}f^{(p,q)}(x,y) =sumli...
