On the sharpness of embeddings of Hölder spaces into Gaussian Besov spaces
Stefan Geiss
For an interpolation pair of Banach spaces with we use vectors that satisfy an extremal property with respect to the…
Extrapolation of Vector valued Rearrangement Operators
Stefan Geiss, Paul F. X. Mueller
We study the extrapolation properties of vector valued rearrangement operators acting on the normalized Haar basis in
Haar Type and Carleson Constants
Stefan Geiss, Paul F. X. Mueller
We determine the sub-collections of the dyadic intervals that are able to detect the Haar type of a Banach space. The underlying dichotomy is expressed in terms of the Carleson pac…
Type and cotype with respect to arbitrary orthonormal systems
Stefan Geiss, Marius Junge
Let $\on_{k \in \nz}$ be an orthonormal system on some -finite measure space $(\Om,p)$. We study the notion of cotype with respect to for an operator between two Banach…
Lower estimates of random unconditional constants of Walsh-Paley martingales with values in banach spaces
Stefan Geiss
For a Banach space X we define RUMD_n(X) to be the infimum of all c>0 such that (AVE_{ε_k =\pm 1} || \sum_1^n epsilon_k (M_k - M_{k-1} )||_{L_2^X}^2 )^{1/2} <= c || M_n ||_{L_2^X}…
