New examples of harmonic maps to the hyperbolic plane via Bäcklund transformation
Giannis Polychrou, Effie Papageorgiou, Anestis Fotiadis +1
We study harmonic maps from a subset of the complex plane to a subset of the hyperbolic plane. In \cite{FotDask}, harmonic maps are related to the sinh-Gordon equation and a B{ä}ck…
Beltrami equation for the harmonic diffeomorphisms between surfaces
Anestis Fotiadis, Costas Daskaloyannis
In this article it is shown that the study of harmonic diffeomorphisms, with nonvanishing Hopf differential, reduces to the study of the Beltrami equation of a certain type: the im…
Algebraic Calculation of the Energy Eigenvalues for the Nondegenerate Three-Dimensional Kepler-Coulomb Potential
Yannis Tanoudis, Costas Daskaloyannis
In the three-dimensional flat space, a classical Hamiltonian, which has five functionally independent integrals of motion, including the Hamiltonian, is characterized as superinteg…
Variants of bosonisation in Parabosonic algebra. The Hopf and super-Hopf structures
K. Kanakoglou, C. Daskaloyannis
Parabosonic algebra in finite or infinite degrees of freedom is considered as a -graded associative algebra, and is shown to be a -graded (or: super…
Quadratic algebras for three dimensional non degenerate superintegrable systems with quadratic integrals of motion
Y. Tanoudis, C. Daskaloyannis
The three dimensional superintegrable systems with quadratic integrals of motion have five functionally independent integrals, one among them is the Hamiltonian. Kalnins, Kress and…
Paraboson quotients. A braided look at Green ansatz and a generalization
K. Kanakoglou, C. Daskaloyannis
Bosons and Parabosons are described as associative superalgebras, with an infinite number of odd generators. Bosons are shown to be a quotient superalgebra of Parabosons, establish…
