Let $T=\biggl(\begin{matrix} A&0\\U&B\end{matrix}\biggr)$ be a formal triangular matrix ring, where $A$ and $B$ are rings $U$ is $(B, A)$-bimodule. We first give some computing formulas of projective, injective, flat $FP$-injective dimensions special left $T$-modules. Then we establish (weak) global $T$. It proven that (1) If $U_{A}$ $_{B}U$ $lD(A)\neq lD(B)$, then $lD(T)={\rm m...

In this paper, we consider the large deviations principles (LDPs) for stochastic linear Schrödinger equation and its symplectic discretizations. These numerical discretizations are spatial semi-discretization based on spectral Galerkin method, further full with schemes in temporal direction. First, by means of abstract Gärtner–Ellis theorem, prove that observable $B_{T}=\frac {u(T)}{T}$ , T > 0...

this paper is concerned with the following elliptic system:$$ left{ begin{array}{ll} -triangle u + b(x)nabla u + v(x)u=g(x, v), -triangle v - b(x)nabla v + v(x)v=f(x, u), end{array} right. $$ for $x in {r}^{n}$, where $v $, $b$ and $w$ are 1-periodic in $x$, and $f(x,t)$, $g(x,t)$ are super-quadratic. in this paper, we give a new technique to show the boundedness of cerami sequences and establi...

Abstract In this article, we deal with the existence of solutions for following second-order differential equation: $$\begin{aligned} \left\{ \begin{aligned}&amp;u''(t)=f(t,u(t))+h(t)\\&amp;u(a)-u(b)= u'(a)-u'(b)=0, \end{aligned}\right. \end{aligned}$$ <mml:...

Error bounds in approximating the Riemann-Stieltjes integral in terms of some moments of the integrand are given. Applications for p convex functions and in approximating the Finite Foureir Transform are pointed out as well. 1. Introduction In order to approximate the Riemann-Stieltjes integral R b a f (t) du (t) with the arguably simpler expression (1.1) u (b) u (a) b a Z b a f (t) dt; where R...
