Fine Structure of Matrix Darboux-Toda Integrable Mapping [PDF]

open access: yes, 1998
We show here that matrix Darboux-Toda transformation can be written as a product of a number of mappings. Each of these mappings is a symmetry of the matrix nonlinear Shrodinger system of integro-differential equations. We thus introduce a completely new

Indecomposable Positive Maps in Matrix Algebras [PDF]

open access: yesCanadian Mathematical Bulletin, 1988
AbstractWe prove that Choi's map in M3 cannot be written as the sum of a 2-positive map and a 2-copositive map. We also provide other examples of positive maps in Mn which cannot be written as the sum of an n-positive map and a 2-copositive map.

Some New Cauchy Sequence Spaces

open access: yesUniversal Journal of Mathematics and Applications, 2018
In this paper, our goal is to introduce some new Cauchy sequence spaces. These spaces are defined by Cauchy transforms. We shall use notations $C_{\infty }\left( s,t\right) $, $C\left( s,t\right) $ and $C_{0}\left( s,t\right) ~$for these new sequence ...

Mapping the Matrix: The Ways of Neocortex [PDF]

open access: yesNeuron, 2007
While we know that the neocortex occupies 85% of our brains and that its circuits allow an enormous flexibility and repertoire of behavior (not to mention unexplained phenomena like consciousness), a century after Cajal we have very little knowledge of the details of the cortical circuits or their mode of function.

A study on Matrix Domain of Riesz-Euler Totient Matrix in the Space of $p$-Absolutely Summable Sequences

open access: yesCommunications in Advanced Mathematical Sciences, 2021
In this study, a special lower triangular matrix derived by combining Riesz matrix and Euler totient matrix is used to construct new Banach spaces. $\alpha-$,$\beta-$,$\gamma-$duals of the resulting spaces are obtained and some matrix operators ...

Common Fixed-Point Results in Ordered Left (Right) Quasi-b-Metric Spaces and Applications

open access: yesJournal of Mathematics, 2020
We use the notions of left- and right-complete quasi-b-metric spaces and partial ordered sets to obtain a couple of common fixed-point results for strictly weakly isotone increasing mappings and relatively weakly increasing mappings, which satisfy a pair

Renormalization analysis of catalytic Wright-Fisher diffusions [PDF]

open access: yes, 2005
Recently, several authors have studied maps where a function, describing the local diffusion matrix of a diffusion process with a linear drift towards an attraction point, is mapped into the average of that function with respect to the unique invariant ...

On (m,n)-Derivations of Some Algebras

open access: yesDemonstratio Mathematica, 2014
Let A be a unital algebra, δ be a linear mapping from A into itself and m, n be fixed integers. We call δ an (m, n)-derivable mapping at Z, if mδ(AB) + nδ(BA) = mδ(A)B + mAδ(B) + nδ(B)A for all A,B ∈ A with AB = Z.
