The behavior of the solutions of these problems when the number of holes increases without bound and their diameter approaches zero is studied. A Lyapunov space r with the Lyapunov index equal to unity in a three-dimensional space R3 is considered: D = Rs\E = D+ U 0- U S, S U Sj; I = r\s. In the domain D, the second boundary value problem for the Helmholtz equation is Au (P) + klit (P) (P); au (P)0 Card 1/3 an - 1Z_ ) UDC: 51M46.9 ACC NRs AP6015958 0 Bounds of the Green functions Gi(P, Qp i;k) and Ge(P, qp iA) of the internal and external Neumann boundary value problem au (P) Au (P) Mu (P) = 0; I V (P) are introduced.

PURPOSE: This book is intended for scientists working in the field of mathematics and theoretical physics; it may also be useful to advanced students interested in the spectral theory of differential equations. COVERAGE: The book deals with one of the new problems in the spectral theory of differential equations - the so-called inverse problem of the quantum theory of scatter. This problem, which has its origin in theoretical physics, is, in the simplest case., reduced to the formation of the differential operator,- based on the asymptotic behavior of its normed eigenfunctions at infinity. The book contains a rigorous investigation and solution of the above-mentioned problem. The mathematical apparatus developed for this may also find application in other related problems. Conventionally, problems that indicate which spectral data CaX&-I/& Inverse Problem of the Scatter Theory SOV/5164 unequivocally determine the differential operator, and present methods for re- ducing the operator according to these data, have bew called ninverse spectral- ang.lysisn problems. The following personalities are mentioned: V.A. Ambartsanyan, V.A. Marchenko, M.G. Weyn, I.M. Gellfand, and B.M. Levitan. There are 14 references: 10 Soviet -nd 4 Euglish.

The author shows that the assertion I, can be extended to arbitrary non- selfadjoint-boundary value problems (A)-(B). With-the aid of the method of I.M.-Ge-11fanA and B.M. Levitan (Ref.5) the author finds conditions which must be satisfied by a generalized function over Z in order that it is a spectral function of a problem (A)-(B). The analytic form of the spectral function can be determined in exceptional cases.
