چکیده
In this paper we will study the existence of fundamental solutions for the explicit and implicit backward time dependent Schödinger equation, via discrete Fourier transform and its symbol for the Laplace operator. In both cases we will prove that the discrete fundamental solutions obtained converges to the continuous fundamental solution in the l1−norm sense.

A finite difference method for the smooth solution of linear Volterra integral equations
The present paper proposes a fast numerical method for the linear Volterra integral equations withregular and weakly singular kernels having smooth solutions. This method is based on the approx-imation of the kernel, to simplify the integral operator and then discretization of the simpliedoperator using a forward dierence formula. To analyze and verify the accuracy of the method, weexamine samp...

We consider the generalized Schrr odinger operator ? + where is a nonnegative Radon measure in R n , n 3. Assuming that satisses certain scale-invariant Kato condition and doubling condition, we establish the following bounds for the fundamental solution of ? + in R n : where d(x; y;) is the distance function for the modiied Agmon metric m(x;)dx 2 associated with. We also study the boundedness ...
متن کاملInverse eigenvalue problem via finite-difference three-diagonal Schrödinger operator
In present article the self-contained derivation of eigenvalue inverse problem results is given by using a discrete approximation with three-diagonal SturmLiouville operator on a finite interval. It is demonstrated that inverse problem procedure is nothing else than well known Gram-Schmidt orthonormalization in Euclidean space for special vectors numbered by space coordinate index. All the resu...
متن کاملExplicit representations of Pollaczek polynomials corresponding to an exactly solvable discretisation of hydrogen radial Schrödinger equation
Abstract. We consider an exactly solvable discretisation of the radial Schrödinger equation of the hydrogen atom with l = 0. We first examine direct solutions of the finite difference equation and remark that the solutions can be analytically continued entire functions. A recursive expression for the coefficients in the solution is obtained. The next step is to identify the related three-term r...
متن کاملA VARIATIONAL APPROACH TO THE EXISTENCE OF INFINITELY MANY SOLUTIONS FOR DIFFERENCE EQUATIONS
The existence of infinitely many solutions for an anisotropic discrete non-linear problem with variable exponent according to p(k)–Laplacian operator with Dirichlet boundary value condition, under appropriate behaviors of the non-linear term, is investigated. The technical approach is based on a local minimum theorem for differentiable functionals due to Ricceri. We point out a theorem as a spe...
