Abstract: In this paper, we prove the optimal upper bound λn λm ≤ ( n m )2 of vibrating string −y = λρ(x)y, with Dirichlet boundary conditions for single-well densities. The proof is based on the…

Abstract: Newtonian, undamped motion in single-well potentials belong to a class of well-studied conservative systems. Here, we investigate and compare long-time properties of fully deterministic motions in single-well potentials with analogous randomized systems. We consider a…

Abstract: Single-well imaging (SWI) is a borehole measurement technique for detecting geologic structures outside a borehole by using arrays of receivers to record the waves reflected from these structures. The asymptotic solutions of P-P, SV-SV, and…
