A Poisson boundary for topological semigroups

Archiv der Mathematik, 2014
\textit{H. Furstenberg} [Ann. Math. (2) 77, 335--386 (1963; Zbl 0192.12704)] proved an integral representation formula in terms of the Poisson boundary for functions harmonic with respect to a Borel measure on a group \(G\) under the assumption that the group is a connected semi-simple Lie group with finite centre and no compact factors.

Values on the Topological Boundary of Tubes

1988
Holomorphic functions in tube domains in ℂn which generalize the Hardy Hp functions are shown to have boundary values on the topological boundary of the tube. The boundary values are obtained restrictedly or unrestrictedly in Lp and in the distribution space \( {\text {K}}_{1}^{\prime}\).

The Topological Structure of Grain Boundaries

1990
It is shown that grain boundaries are quasiperodic tilings made of inflatable sequences of structural units. A general grain boundary is a quasiperodic grid of dislocations with the same inflation multiplier (a quadratic irrational) in every direction.
