The Dirichlet problem is considered on the junction of thin quantum waveguides (of thickness h ? 1) in the shape of an infinite two-dimensional ladder. Passage to the limit as h → +0 is discussed. It is shown that the asymptotically correct transmission conditions at nodes of the corresponding one-dimensional quantum graph are Dirichlet conditions rather than the conventional Kirchhoff transmission conditions. The result is obtained by analyzing bounded solutions of a problem in the T-shaped waveguide that the boundary layer phenomenon. 相似文献

We prove that the so-called Smoluchowski-Kramers approximation holds for a class of partial differential equations perturbed
by a non-Gaussian noisy term. Namely, we show that the solution of the one-dimensional semi-linear stochastic damped wave
equations
, u(0) = u0, ut (0) = v0, endowed with Dirichlet boundary conditions, converges as the parameter μ goes to zero to the solution of the semi-linear
stochastic heat equation
, u(0) = u0, endowed with Dirichlet boundary conditions.

Let q ⩾ 3 be an integer, let χ denote a Dirichlet character modulo q. For any real number a ⩾ 0 we define the generalized Dirichlet L-functions
$
L(s,\chi ,a) = \sum\limits_{n = 1}^\infty {\frac{{\chi (n)}}
{{(n + a)^s }},}
$
L(s,\chi ,a) = \sum\limits_{n = 1}^\infty {\frac{{\chi (n)}}
{{(n + a)^s }},}

Let be the first Dirichlet eigenfunction on a connected bounded C
1,α-domain in and the corresponding Dirichlet heat kernel. It is proved that where λ2 > λ1 are the first two Dirichlet eigenvalues. This estimate is sharp for both short and long times. Bounded Lipschitz domains,
elliptic operators on manifolds, and a general framework are also discussed.

We establish the existence of positive solutions for the second order singular semipositone coupled Dirichlet systems $$\left\{ \begin{aligned} &x{''} +f_1 \bigl(t,y(t)\bigr)+e_1(t)=0, \\ &y{''} +f_2\bigl(t,x(t) \bigr)+e_2(t)=0, \\ &x(0)=x(1)=0,\qquad y(0)=y(1)=0. \end{aligned} \right. $$ The proof relies on Schauder’s fixed point theorem. 相似文献

This paper is concerned with a study of bounded perturbations of resonant linear problems. It follows from our results that for certain types of bounded domains Ω ? Rn, n ≥ 2, the Dirichlet problem $\matrix{\Delta u+\lambda_{1}u+g(u)=h(x),\ \ \ x\in\Omega\cr \quad\quad\quad\quad\quad\quad u=0,\ \ \ x\in\partial\Omega,}$ has infinitely many positive solutions, in case λ1 is the principal eigenvalue of ?Δ subject to trivial Dirichlet boundary conditions, g is a nontrivial periodic nonlinearity of zero mean and ∫03A9h(x)?(x)dx = 0, where ? is an eigenfunction corresponding to λ1. 相似文献

The existence of radial solutions of Δu + λg(|x|)f(u) = 0 in annuli with Dirichlet(Dirichlet/Neumann) boundary conditions is investigated.It is proved that the problems have at least two positive radial solutions on any annulus if f is superlinear at 0 and sublinear at ∞. 相似文献

In this paper, we show that a multiplication operator on the Dirichlet space D is unitarily equivalent to Dirichlet shift of multiplicity n + 1 (n ≥ 0) if and only if its symbol is c zn+1 for some constant c. The result is very different from the cases of both the Bergman space and the Hardy space. 相似文献
