Extensions of the matrix Gelfand-Dickey hierarchy from generalized Drinfeld-Sokolov reduction [PDF]
The $p\times p$ matrix version of the $r$-KdV hierarchy has been recently treated as the reduced system arising in a Drinfeld-Sokolov type Hamiltonian symmetry reduction applied to a Poisson submanifold in the dual of the Lie algebra $\widehat{gl}_{pr ...

M-matrix and inverse M-matrix extensions
A class of matrices that simultaneously generalizes the M-matrices and the inverse M-matrices is brought forward and its properties are reviewed. It is interesting to see how this class bridges the properties of the matrices it generalizes and provides a

P-Matrix Reasoning and Information Intelligent Mining
Abstract P-sets (P stand for Packet) and P-matrix are novel and effective mathematical tools for studying dynamic information systems. In this paper, the concept of P-information mining is given by using the dynamic characteristics of P-sets and P-matrix structure.

Dynamical CP Violation in the Early Universe and Leptogenesis [PDF]
In a recent publication, we suggested a mechanism for obtaining dynamical CP violation in the early Universe based on the out-of-equilibrium evolution of complex scalar fields.

P matrix properties, injectivity, and stability in chemical reaction systems [PDF]
In this paper we examine matrices which arise naturally as Jacobians in chemical dynamics. We are particularly interested in when these Jacobians are P matrices (up to a sign change), ensuring certain bounds on their eigenvalues, precluding certain ...

The combinatorially symmetric P-matrix completion problem
An n-by-n real matrix is called a P -matrix if all its principal minors are positive. The P -matrix completion problem asks which partial P -matrices have a completion to a P -matrix. Here, we prove that every partial P -matrix with combinatorially symmetric speci ed entries has a P -matrix completion.

The almost semimonotone matrices
A (strictly) semimonotone matrix A ∈ ℝn×n is such that for every nonzero vector x ∈ ℝn with nonnegative entries, there is an index k such that xk > 0 and (Ax)k is nonnegative (positive).

Multidimensional extension of the generalized Chowla-Selberg formula [PDF]
After recalling the precise existence conditions of the zeta function of a pseudodifferential operator, and the concept of reflection formula, an exponentially convergent expression for the analytic continuation of a multidimensional inhomogeneous ...

The complex-type Padovan-p sequences [PDF]
In this paper, we define the complex-type Padovan-p sequence and then give the relationships between the Padovan-p numbers and the complex-type Padovan-p numbers.
