$\mathcal C$-graph automatic groups
We generalize the notion of a graph automatic group introduced by Kharlampovich, Khoussainov and Miasnikov by replacing the regular languages in their definition with more powerful language classes. For a fixed language class C, we call the resulting groups C-graph automatic. We prove that the class of C-graph automatic groups is closed under change of generating set, direct and free product fo...
متن کاملQuantum Rotors and Their Symmetries
Quantum rotors have been extensively studied in the past and turned out to be powerful theoretical tools in exploring the microscopic symmetries of the examined objects, but the variety of possibilities that their theory offers has been explored mainly in molecular physics. Nuclear physics applications, although numerous, have been primarily limited to the quantum Hamiltonians corresponding to ...
متن کاملTight Frames and their Symmetries
The aim of this paper is to investigate symmetry properties of tight frames, with a view to constructing tight frames of orthogonal polynomials in several variables which share the symmetries of the weight function, and other similar applications. This is achieved by using representation theory to give methods for constructing tight frames as orbits of groups of unitary transformations acting o...
متن کاملC∞−Symmetries and Reduction of Equations Without Lie Point Symmetries
It is proved that several usual methods of reduction for ordinary differential equations, that do not come from the Lie theory, are derived from the existence of C∞ -symmetries. This kind of symmetries is also applied to obtain two successive reductions of an equation that lacks Lie point symmetries but is a reduced equation of another one with a three dimensional Lie algebra of point symmetrie...
