Product Description: Infinite interval problems abound in nature and yet until now there has been no book dealing with such problems. The main reason for this seems to be that until the 1970's for the infinite interval problem all the theoretical results available required rather technical hypotheses and were applicable only to narrowly defined classes of problems...read more

Product Description: This monograph presents an up-to-date account of the theory of right focal point boundary value problems for differential and difference equations. Topics include existence and uniqueness, Picard's method, quasilinearisation, necessary and sufficient conditions for right disfocality, right and eventual disfocalities, Green's functions, monotone convergence, continuous dependence and differentiation with respect to boundary values, infinite interval problems, best possible results, control theory methods, focal subfunctions, singular problems, and problems with impulse effects...read more
