Minimal projections onto spaces of polynomials on real euclidean spheres

Andreas Defant, Daniel Galicer, Martín Mansilla +2

We investigate projection constants within classes of multivariate polynomials over finite-dimensional real Hilbert spaces. Specifically, we consider the projection constant for sp…

Hypercontractivity and strips of convergence in Hardy spaces of general Dirichlet series

Daniel Carando, Andreas Defant, Felipe Marceca +2

For a general Dirichlet series $\sum a_{n} e^{- λ_{n} s}$ with frequency $λ = (λ_{n})_{n}$ , we study how horizontal translation (i.e. convolution with a Poisson kernel) improves its integrabi…
