Multidimensional extension of the Morse-Hedlund theorem
A celebrated result of Morse and Hedlund, stated in 1938, asserts that a sequence x over a finite alphabet is ultimately periodic if and only if, for some n, the number of different factors of length n appearing in x is less than n+1. Attempts to extend this fundamental result, for example, to higher dimensions, have been considered during the last fifteen years. Let d ≥ 2. A legitimate extensi...
متن کاملIsospectral Hulthén Potential
Supersymmetric Quantum Mechanics is an interesting framework to analyze nonrelativistic quantal problems. Using these techniques, we construct a family of strictly isospectral Hulthén potentials. Isospectral wave functions are generated and plotted for different values of the deformation parameter. Keywords—Hulthén potential, Isospectral Hamiltonian.
متن کاملA New Modification of Morse Potential Energy Function
Interaction of meso — tetrakis (p-sulphonato phenyl) porphyrin (hereafter abbreviated to TSPP)with Na+ has been examined using HF level of theory with 6-31G* basis set. Counterpoise (CP)correction has been used to show the extent of the basis set superposition error (BSSE) on thepotential energy curves. The numbers of Na+ have a significant effect on the calculated potentialenergy curve (includ...
متن کاملOn the Scalar Potential Models from the Isospectral Potential Class
Static field classical configurations in (1+1)-dimensions for new non-linear potential models are investigated from an isospectral potential class and the concept of bosonic zeromode solution. One of the models here considered has a static non-topological configuration with a single vacuum state that breaks supersymmetry. PACS numbers: 11.30.Pb, 03.65.Fd, 11.10.Ef ∗Permanent address: Departamen...
متن کاملA Morse-theoretical Proof of the Hartogs Extension Theorem
100 years ago exactly, in 1906, Hartogs published a celebrated extension phenomenon (birth of Several Complex Variables), whose global counterpart was understood later: holomorphic functions in a connected neighborhood V(∂Ω) of a connected boundary ∂Ω b C (n > 2) do extend holomorphically and uniquely to the domain Ω. Martinelli in the early 1940’s and Ehrenpreis in 1961 obtained a rigorous pro...
