RT Journal Article ID 029e2dcf353feb8b A1 Podlipenko, Yuriy K. A1 Levoshych, Oleg L. A1 Popkov, I. I. T1 On Minimax Estimation in the Problems of Acoustic Wave Diffraction JF Journal of Automation and Information Sciences JO JAI(S) YR 1999 FD 1999-01-04 VO 31 IS 1-3 SP 22 OP 28 K1 Minimax estimation; boundary value problem; Helmholtz equation AB Minimax estimates of functionals of solutions are obtained for systems described by external boundary value problems for the Helmholtz equation under conditions of incomplete information. Determination of minimax estimates is reduced to solution of systems of integro-differential equations.
