A new analysis is presented of the relations between multicomponent friction coefficients and hydration numbers which describe non-ionic and multicomponent solutes transport in membranes in the framework of generalized Spiegler-Kedem-Katchalsky frictional model equations. In the framework of this model the expressions linking the permeability parameters of the membrane (Lp, sigma, omegaik) with...

In this paper we introduce the concept of weakly prime ternary subsemimodules of a ternary semimodule over a ternary semiring and obtain some characterizations of weakly prime ternary subsemimodules. We prove that if $N$ is a weakly prime subtractive ternary subsemimodule of a ternary $R$-semimodule $M$, then either $N$ is a prime ternary subsemimodule or $(N : M)(N : M)N = 0$. If $N$ is a $Q$-...

The main goal of this paper is to introduce the notion 3-L-dendriform algebras which are dendriform version 3-pre-Lie algebras. In fact they algebraic structures behind O-operator They can be also regarded as ternary analogous L-dendriform Moreover, we study generalized derivations Finally, explore spaces quasi-derivations, centroids and quasi-centroids give some properties.

We formulate sufficient conditions for the strong integrability of dressing cosets. provide several sigma-model backgrounds solving those conditions, some them are new and were not so far formulated as The models based on Drinfeld doubles having structure higher-order jet bundles quadratic Lie groups.

Let $\Sigma$ be a finite type surface, and $G$ complex algebraic simple Lie group with algebra $\mathfrak{g}$. The quantum moduli of $(\Sigma,G)$ is quantization the ring functions $X_G(\Sigma)$, variety $G$-characters $\pi_1(\Sigma)$, introduced by Alekseev-Grosse-Schomerus Buffenoir-Roche in mid '90s. It can realized as invariant subalgebra so-called graph algebras, which are $U_q(\mathfrak{g...

let $mathcal{a}$ be a banach algebra and $mathcal{m}$ be a banach $mathcal{a}$-bimodule. we say that a linear mapping $delta:mathcal{a} rightarrow mathcal{m}$ is a generalized $sigma$-derivation whenever there exists a $sigma$-derivation $d:mathcal{a} rightarrow mathcal{m}$ such that $delta(ab) = delta(a)sigma(b) + sigma(a)d(b)$, for all $a,b in mathcal{a}$. giving some facts concerning general...

in a ternary semihyperring, addition is a hyperoperation and multiplicationis a ternary operation. indeed, the notion of ternary semihyperringsis a generalization of semirings. our main purpose of this paper is to introducethe notions of fuzzy hyperideal and fuzzy bi-hyperideal in ternary semihyperrings.we give some characterizations of fuzzy hyperideals and investigateseveral kinds of them.

‎let $l$ be a lie algebra‎, ‎$mathrm{der}(l)$ be the set of all derivations of $l$ and $mathrm{der}_c(l)$ denote the set of all derivations $alphainmathrm{der}(l)$ for which $alpha(x)in [x,l]:={[x,y]vert yin l}$ for all $xin l$‎. ‎we obtain an upper bound for dimension of $mathrm{der}_c(l)$ of the finite dimensional nilpotent lie algebra $l$ over algebraically closed fields‎. ‎also‎, ‎we classi...

We propose a generalization of non-commutative geometry and gauge theories based on ternary Z3-graded structures. In the new algebraic structures we define, we leave all products of two entities free, imposing relations on ternary products only. These relations reflect the action of the Z3-group, which may be either trivial, i.e. abc = bca = cab, generalizing the usual commutativity, or non-tri...

Given a Hamiltonian system $ (M,\omega, G,\mu) where $(M,\omega)$ is symplectic manifold, $G$ compact connected Lie group acting on with moment map \mu:M \rightarrow\mathfrak{g}^{*}$, then one may construct the quotient $(M//G, \omega_{red})$ $M//G := \mu^{-1}(0)/G$. Kirwan used norm-square of map, $|\mu|^2$, as G-equivariant Morse function $M$ to derive formulas for rational Betti numbers $M//...
