Hamiltonian structures for Pais-Uhlenbeck oscillator
Katarzyna Bolonek, Piotr Kosinski
The hamiltonian structures for quartic oscillator are considered. All structures admitting quadratic hamiltonians are classified.
Symmetry algebras for superintegrable systems
C. Gonera, P. Kosinski, M. Majewski +1
It is shown that the symmetry algebra of quantum superintegrable system can be always chosen to be u(N),N being the number of degrees of freedom.
Lorentz-Invariant Interpretation of Noncommutative Space-Time - global version
P. Kosinski, P. Maslanka
The global version of the quantum symmetry defined by Chaichian et al (hep-th/0408069) is constructed.
On threshold amplitudes III: 2 into n processes
Joanna Domienik, Piotr Kosinski
The 2 into n scattering with final particles at rest is discussed. The comparison with purely soft processes allows to identify symmetries responsible for vanishing of certain 2 in…
Minimalisation of uncertainty relations in noncommutative quantum mechanics
Piotr Kosinski, Katarzyna Bolonek
The explicit constrtuction of states saturating uncertainty relations following from basic commutation rules of NCQM is given both in Fock space and coordinate representation
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…
