Inverse problems for discrete Hermite nabla difference equation

Applied Mathematics in Science and Engineering
Inverse problems are studied for discrete Hermite equations with nabla difference including initial value, terminal value and Sturm–Liouville problems. A quantitative study is conducted to obtain the solution.

Classical and Quantum Complexity of the Sturm-Liouville Eigenvalue Problem

, 2005
We study the approximation of the smallest eigenvalue of a Sturm-Liouville problem in the classical and quantum settings. We consider a univariate Sturm- Liouville eigenvalue problem with a nonnegative function q from the class C 2 ([0, 1]) and study the

Operator-pencil treatment of multi-interval Sturm-Liouville equation with boundary-transmission conditions

Қарағанды университетінің хабаршысы. Математика сериясы
This paper is devoted to a new type of boundary-value problems for Sturm-Liouville equations defined on three disjoint intervals (−π,−π+d),(−π+d,π−d) and (π−d,π) together with eigenparameter dependent boundary conditions and with additional transmission

Nonlinear discrete Sturm–Liouville problems

Journal of Mathematical Analysis and Applications, 2005
The paper is devoted to discrete boundary value problems of the form \[ \Delta\left[ p\left( t-1\right) \Delta y\left( t-1\right) \right] +q\left( t\right) y\left( t\right) +\lambda y\left( t\right) =f\left( y\left( t\right) \right) , \] \(t=a+1,\dots,b+1,\) subject to the boundary conditions \[ a_{11}y\left( a\right) +a_{12}\Delta y\left( a\right) =0,\
