Propagation of regularity and positive definiteness: a constructive approach

Jorge Buescu, António Paixão, Claudemir Oliveira

We show that, for positive definite kernels, if specific forms of regularity (continuity, Sn-differentiability or holomorphy) hold locally on the diagonal, then they must hold glob…

Positive-definiteness and integral representations for special functions

Jorge Buescu, António Paixão

We characterize a holomorphic positive definite function defined on a horizontal strip of the complex plane as the Fourier-Laplace transform of a unique exponentially finite me…
