In the studies of acoustic waveguides in ocean, buckling of columns with
variable cross sections in applied elasticity, transverse vibrations in non-homogeneous strings, etc., we encounter a new class of problems of the
type defined on an interval and
on the adjacent interval satisfying
certain matching conditions at the interface point .
Here in Part I, we constructed a fundamental system for and
derive certain estimates for the same. Later, in Part II, we shall consider
four types of boundary value problems associated with and study
the corresponding spectra.
