Zimnev, M. M.; Popov, I. Yu. Selection of parameters for a model of cracks of zero width. (English. Russian original) Zbl 0669.35008 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.
