Jordanian deformation of the open XXX-spin chain
P. P. Kulish, N. Manojlovic, Z. Nagy
The general solution to the reflection equation associated with the jordanian deformation of the SL(2) invariant Yang R-matrix is found. The same K-matrix is obtained by the specia…
A Deformation Quantization Theory for Non-Commutative Quantum Mechanics
N. C. Dias, M. A. de Gosson, F. Luef +1
We show that the deformation quantization of non-commutative quantum mechanics previously considered by Dias and Prata can be expressed as a Weyl calculus on a double phase space.…
Symmetries of spin systems and Birman-Wenzl-Murakami algebra
P. P. Kulish, N. Manojlovic, Z. Nagy
We consider integrable open spin chains related to the quantum affine algebras U_q(o(3)) and U_q(A_2^{(2)}). We discuss the symmetry algebras of these chains with the local C^3 spa…
Wigner Measures in Noncommutative Quantum Mechanics
C. Bastos, N. C. Dias, J. N. Prata
We study the properties of quasi-distributions or Wigner measures in the context of noncommutative quantum mechanics. In particular, we obtain necessary and sufficient conditions f…
A Spectral Bernstein Theorem
Pedro Freitas, Isabel Salavessa
We study the spectrum of the Laplace operator of a complete minimal properly immersed hypersurface in . (1) Under a volume growth condition on extrinsic balls and a c…
Bifurcations of Liouville Tori in Elliptical Billiards
Vladimir Dragovic, Milena Radnovic
A detailed description of topology of integrable billiard systems is given. For elliptical billiards and geodesic billiards on ellipsoid, the corresponding Fomenko graphs are const…
Elliptic Curves and a New Construction of Integrable Systems
Vladimir Dragovic, Borislav Gajic
A class of elliptic curves with associated Lax matrices is considered. A family of dynamical systems on e(3) parametrized by polynomial a with above Lax matrices are constructed. F…
Singular Manakov Flows and Geodesic Flows on Homogeneous Spaces
Vladimir Dragovic, Borislav Gajic, Bozidar Jovanovic
We prove complete integrability of the Manakov-type SO(n)-invariant geodesic flows on homogeneous spaces , for any choice of , $k…
