Abstract:  

Measure Differential Equations (MDE) can be considered as the limiting case of the usual Differential Equations. In this talk, by taking the spatial oscillation of 1D strings with general distributions of masses as an example, we will discuss how solutions and eigenvalues of MDE depend on measures in MDE. As a consequence of the so-called completely continuous dependence, we will show that ODEs and Algebraic Equations (AEs) can be mutually approximated, including their solutions, eigenvalues, etc. These results may be used to solve some applied problems, and even to yield some numerical methods for finding eigenvalues.
