U.S.S.R. Comput. Math. Math. Phys. 27, No. 2, 99-102 (1987); translation from Zh. Vychisl. Mat. Mat. Fiz. 27, No. 3, 466-470 (1987).
Based on the theory of extended symmetric operators, the authors discuss the problem of choice of parameters for a model of cracks of zero width. Some specific examples of diffraction problems are discussed.
