Abstract

In the studies of acoustic waveguides in ocean, buckling of columns with variable cross sections in applied elasticity, transverse vibrations in nonhomogeneous strings, etc., we encounter a new class of problems of the type L1y1≡−y1′​′+q1(x)y1=λy1 defined on an interval [d1,d2] and L2y2≡−y2′​′+q2(x)y2=λy2 defined on the interval [d2,d3] satisfying certain matching conditions at the interface point x=d2.

Earlier, in Part I, we constructed a fundamental system for (L1,L2) and derived certain estimates for the same.

Here, in Part II, we consider four types of boundary value problems associated with (L1,L2) and study the corresponding spectra.
