PY - 2011 TI - On the Determination of Asymptotic Formula of the Nodal Points for Differential Pencils with Separated Boundary Conditions JO - Journal of Mathematics and Computer Science SP - 176--178 VL - 3 IS - 2 AB - In this work, we solve the inverse nodal problem for the diffusion operator on a finite interval with separated boundary conditions. We investigation the oscillation of the eigenfunctions and derive an asymptotic formula for the nodal points. Uniqueness theorem is proved, and a constructive procedure for the solution is provided.
