Quasi-Invariance of the Dirichlet series kernels, Analytic symbols and Homogeneous operators

Sameer Chavan, Chaman Kumar Sahu

For a scalar matrix $a = (a_{m, n})_{m, n = 1}^{\infty},$ the Dirichlet series kernel $κ_{a}$ is the double Dirichlet series $κ_{\mathbf a}(s, u) = \sum_{m, n =1}^{\inf…

Dirichlet polynomials and a moment problem

Sameer Chavan, Chaman Kumar Sahu

Consider a linear functional $L$ defined on the space $D [s]$ of Dirichlet polynomials with real coefficients and the set $D_{+} [s]$ of non-negative elements in $\ma…
