Projection constants for spaces of multivariate polynomials
Andreas Defant, Daniel Galicer, Martín Mansilla +2
The general problem we address is to develop new methods in the study of projection constants of Banach spaces of multivariate polynomials. The relative projection constant $\bolds…

Two-weight Norm Estimates for Multilinear Fractional Integrals in Classical Lebesgue Spaces
Vakhtang Kokilashvili, Mieczyslaw Mastylo, Alexander Meskhi
We derive criteria governing two-weight estimates for multilinear fractional integrals and appropriate maximal functions. The two and one weight problems for multi(sub)linear stron…
