Ryll-Wojtaszczyk Formulas for bihomogeneous polynomials on the sphere
Andreas Defant, Daniel Galicer, Martín Mansilla +2
We investigate projection constants for spaces of bihomogeneous harmonic and bihomogeneous polynomials on the unit sphere in finite-dimensional complex Hilbert spaces. Using averag…
Revisiting Operator -Compact Mappings
Javier Alejandro Chávez-Domínguez, Verónica Dimant, Daniel Galicer
We continue our study of the mapping ideal of operator -compact maps, previously introduced by the authors. Our approach embraces a more geometric perspective, delving into the…
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…
On the linear polarization constants of finite dimensional spaces
Daniel Carando, Damián Pinasco, Jorge Tomás Rodríguez
We study the linear polarization constants of finite dimensional Banach spaces. We obtain the correct asymptotic behaviour of these constants for the spaces : they behave…
Lower bounds for norms of products of polynomials on spaces
Daniel Carando, Damian Pinasco, Jorge Tomás Rodríguez
For we obtain sharp inequalities for the supremum of products of homogeneous polynomials on , whenever the number of factors is no greater than the dimension of t…
Orthogonally additive holomorphic functions of bounded type over
Daniel Carando, Silvia Lassalle, Ignacio Zalduendo
It is known that all -homogeneous orthogonally additive polynomials over are of the form Thus factors all orthogonally additi…
