Dyck paths are classical Catalan objects. The peak distribution of Dyck paths is an important topic of combinatorics, and further the representation of symmetric groups.
One parameter family of indecomposable optimal entanglement witnesses arising from generalized Choi maps
generalized Choi maps One parameter family Quantum Physics
2011/10/8
Abstract: In the recent paper [Chru\'{s}ci\'{n}ski and Wudarski, arXiv:1105.4821], it was conjectured that the entanglement witnesses arising from some generalized Choi maps are optimal. We show that ...
Non Gaussian extrema counts for CMB maps

2011/9/30
Abstract: In the context of the geometrical analysis of weakly non Gaussian CMB maps, the 2D differential extrema counts as functions of the excursion set threshold is derived from the full moments ex...
Global well-posedness and scattering for Skyrme wave maps
Wave maps Skyrme model Adkins-Nappi model global existence scattering theory
2011/7/28
Abstract: We study equivariant maps corresponding to the classical Skyrme model and the Adkins-Nappi model, for which we prove global existence and scattering in critical Sobolev-Besov spaces.
Graded Hopf Maps and Fuzzy Superspheres
Graded Hopf Maps Fuzzy Superspheres High Energy Physics - Theory
2011/7/28
Abstract: We argue supersymmetric generalizations of fuzzy two- and four-spheres based on the unitary-orthosymplectic algebras, $UOSp(N|2)$ and $UOSp(N|4)$, respectively. Supersymmetric version of Sch...
Exposed faces for decomposable positive linear maps arising from completely positive maps
decomposable positive maps exposed faces product vectors
2011/7/25
Abstract: Let $D$ be a space of $2\times n$ matrices. Then the face of the cone of all completely positive maps from $M_2$ into $M_n$ given by $D$ is an exposed face of the bigger cone of all decompos...
A recursive approach to the O(n) model on random maps via nested loops
recursive O(n) model random maps via nested loops
2011/7/25
Abstract: We consider the O(n) loop model on tetravalent maps and show how to rephrase it into a model of bipartite maps without loops. This follows from a combinatorial decomposition that consists in...

Poisson Yang-Baxter maps with binomial Lax matrices
Poisson Yang-Baxter maps binomial Lax matrices Quantum Algebra
2011/7/25
Abstract: A construction of multidimensional parametric Yang-Baxter maps is presented. The corresponding Lax matrices are the symplectic leaves of first degree matrix polynomials equipped with the Skl...
Affine Maps of the Polarization Vector for Quantum Systems of Arbitrary Dimension
Affine Maps the Polarization Vector Quantum Systems Arbitrary Dimension
2010/11/4
The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affine map which provides...
Open system quantum dynamics with correlated initial states, not completely positive maps and non-Markovianity
quantum dynamics non-Markovianity Quantum Physics
2010/11/8
Dynamical A and B maps have been employed extensively by Sudarshan and co-workers to investigate open system evolution of quantum systems. A canonical structure of the A-map is introduced here. It is ...
Regular hyperbolicity, dominant energy condition and causality for Lagrangian theory of maps
Regular hyperbolicity dominant energy condition causality for Lagrangian theory of maps
2010/12/21
The goal of the present paper is three-fold. First is to clarify the connection between the dominant energy condition and hyperbolicity properties of Lagrangian field theories.
Entanglement evolution of non-trace-preserving maps
Entanglement evolution non-trace-preserving maps
2010/10/21
By solving the Schrodinger equation one obtains the whole energy spectrum, both the bound and
the continuum states. If the Hamiltonian depends on a set of parameters, these could be tuned to a trans...
Globally coupled chaotic maps with bistable behaviour: Large deviations
chaotic maps bistable behaviour self consistent Perron-Frobenius operator
2010/4/6
For a system of globally coupled chaotic maps with bistable behaviour we relate the rate function for large deviations in the system size at finite time to dynamical properties of the self consistent ...
The Bolztmann echo (BE) is a measure of irreversibility and sensitivity to perturbations for non-isolated systems. Recently, different regimes of this quantity were described for chaotic systems. Ther...
