Convergent Quantum Normal Forms, ${\mathcal P}{\mathcal T}$-symmetry and reality of the spectrum
Convergent Quantum Normal Forms reality of the spectrum Mathematical Physics

2012/6/19
A class of non-selfadjoint, $\PT$-symmetric operators is identified similar to a self-adjoint one, thus entailing the reality of the spectrum. The similarity transformation is explicitly constructed t...
Amalgamated Products of Groups II: Measures of Random Normal Forms
Amalgamated Products Measures of Random Normal Forms Group Theory

Abstract: Let $G=\mathop{A\ast B}\limits_C$ be an amalgamated product of finite rank free groups $A$, $B$ and $C$. We introduce atomic measures and corresponding asymptotic densities on a set of norma...

2010/12/6
Matrices over the ring of formal power series are considered. Normal forms wit respect to various sub-groups of the two-sided transformations are constructed. The construc-tion is based on the special...

Non-commutativity is ubiquitous in mathematical modeling of reality and in many cases same algebraic structures are implemented in different situations. Here we consider the canonical commutation rel...
Natural Density Distribution of Hermite Normal Forms of Integer Matrices
Natural density Hermite normal form integer lattices

2010/12/13
The Hermite Normal Form (HNF) is a canonical representation of matrices over any principal
ideal domain. Over the integers, the distribution of the HNFs of randomly looking matrices is far from unifo...

Let (P) = (0, 1, . . . , d) be the -vector of an integral polytope P ⊂ RN of dimension d. By means of Hermite normal forms of square matrices,the problem of classifying the possible integra...
Conservation laws and normal forms of evolution equations
Conservation laws normal forms evolution equations

2010/4/6
We study local conservation laws for evolution equations in two independent variables. In particular, we present normal forms for the equations admitting one or two low-order conservation laws. Exampl...
