Symmetrizing Evolutions
The importance of the notion of symmetry in quantum theory cannot be overstimated [1]. The associated statespace decomposition into dynamically invariant sectors is a highly desirable property in that it can strongly simplify the analysis of the system evolution. Suppose that on the state-space H of a quantum system S acts a group G via a representation ρ. In general the Hamiltonian H of S is n...
متن کاملRandom Evolutions
This article gives a short presentation of random evolutions. At first, the following two examples are presented: dynamical stochastic systems and increment processes both in Markov media. After, an introduction to semi-Markov Random evolution in a Banach space is given, where the previous evolutionary systems are obtained as particular cases. Finally, two abstract limit theorems of average and...
متن کاملSemigroup Structure Underlying Evolutions
A member of a class of evolution systems is defined by averaBing a oneparameter family of invertible transformations G with a semigroup T The resulting evolution system, U(t,s) G(t)T(t-s)G(s) -1, preserves continuity and strong continuity, and in case G is a linear family, may have an identifiable generator and resolvent both of which are constructed from T. Occurrences of the class of evolutio...
متن کاملEvolutions in typesetting systems
Using text previewers to browse code and documentation has uncovered some of the basic limitations of classical typesetting systems. Problems arise from the use of embedded markup, the reliance on context-free grammars, and monolithic typesetter design. Some aspects of each of these problems are discussed. A typesetter architecture is proposed that does not require markup or grammars, and that ...
متن کاملHarmonic evolutions on graphs
We define the harmonic evolution of states of a graph by iterative application of the harmonic operator (Laplacian over Z2). This provides graphs with a new geometric context and leads to a new tool to analyze them. The digraphs of evolutions are analyzed and classified. This construction can also be viewed as a certain topological generalization of cellular automata. MSC: 05C50, 15A33, 05C75, ...
