Solitons on nanotubes and fullerenes as solutions of a modified non-linear Schroedinger equation
Yves Brihaye, Betti Hartmann
Fullerenes and nanotubes consist of a large number of carbon atoms sitting on the sites of a regular lattice. For pratical reasons it is often useful to approximate the equations o…
On linear operators with an invariant subspace of functions
Yves Brihaye
Let us denote , the finite dimensional vector spaces of functions of the form where and are arbitrary polynomials of degre…
A simplified model for monopole catalysis of nucleon decay
Y. Brihaye, V. A. Rubakov, D. H. Tchrakian +1
We present a simple model where a nucleon is treated as the Skyrmion, both monopole and Skyrmion are smooth solutions of the classical field equations,the baryon number non-conserv…
Poisson-Lie structures on Galilei group
Y. Brihaye, E. Kowalczyk, P. Maslanka
The complete list of Poisson-Lie structures on 4-d Galilei group is presented.
spl(p,q) superalgebra and differential operators
Yves Brihaye, Stefan Giller, Piotr Kosinski
Series of finite dimensional representations of the superalgebras spl(p,q) can be formulated in terms of linear differential operators acting on a suitable space of polynomials. We…
On the relations between osp(2,2) and the quasi exactly solvable systems
Yves Brihaye, Stefan Giller, Piotr Kosinski
By taking a product of two sl(2) representations, we obtain the differential operators preserving some space of polynomials in two variables. This allows us to construct the repres…
