Exact evolution operator on non-compact group manifolds
Free quantal motion on group manifolds is considered. The Hamiltonian is given by the Laplace – Beltrami operator on the group manifold, and the purpose is to get the (Feynman’s) evolution kernel Kt. The spectral expansion, which produced a series of the representation characters for Kt in the compact case, does not exist for non-compact group, where the spectrum is not bounded. In this work re...

متن کاملThe Universal Net Composition Operator
Petri nets are frequently composed of given nets. Literature suggests a lot of different composition operators, for different purposes and different classes of Petri nets. Formal definitions are frequently surprisingly technical, not matching the intuitively very elegant composition of Petri nets in the framework of their graphical representation. This paper suggests the universal net compositi...
متن کاملUniversal Uniform Eberlein Compact Spaces
A universal space is one that continuously maps onto all others of its own kind and weight. We investigate when a universal Uniform Eberlein compact space exists for weight κ. If κ = 2<κ, then they exist whereas otherwise, in many cases including κ = ω1, it is consistent that they do not exist. This answers (for many κ and consistently for all κ) a question of Benyamini, Rudin and Wage of 1977.
متن کاملControllability for Impulsive Semilinear Functional Differential Inclusions with a Non-compact Evolution Operator
We study a controllability problem for a system governed by a semilinear functional differential inclusion in a Banach space in the presence of impulse effects and delay. Assuming a regularity of the multivalued non-linearity in terms of the Hausdorff measure of noncompactness we do not require the compactness of the evolution operator generated by the linear part of inclusion. We find existenc...
