-estimates for the torsion function and -growth of semigroups satisfying Gaussian bounds
Hendrik Vogt
We investigate selfadjoint -semigroups on Euclidean domains satisfying Gaussian upper bounds. Major examples are semigroups generated by second order uniformly elliptic operat…
On the -theory of -semigroups associated with second-order elliptic operators with complex singular coefficients
A. F. M. ter Elst, Vitali Liskevich, Zeev Sobol +1
We study -theory of second-order elliptic divergence type operators with complex measurable coefficients. The major aspect is that we allow complex coefficients in the main pa…
On the numerical range of generators of symmetric -contractive semigroups
Markus Haase, Peer Christian Kunstmann, Hendrik Vogt
A result by Liskevich and Perelmuter from 1995 yields the optimal angle of analyticity for symmetric submarkovian semigroups on , . C.~Kriegler showed in 2011 that…
Bands in -spaces
Hendrik Vogt, Jürgen Voigt
For a general measure space , it is shown that for every band in there exists a decomposition such that $M=L_p(μ')=\{f\in L_p(μ);f=0\ μ^…
