In this paper, we study the transition densities of pure-jump symmetric Markov processes in ℝd, whose jumping kernels are comparable to radially symmetric functions with mixed polynomial growths.

Multiple zeta functions extend the classical Riemann zeta function to several complex variables by involving multiple summations with distinct exponents. These functions not only encapsulate deep ...

In an isomorphic copy of the ring of symmetric polynomials we study some families of polynomials which are indexed by rational weight vectors. These families include well known symmetric polynomials, ...
