Phys.-Dokl. 39, No. 12, 839-842 (1994); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 339, No. 6, 746-749 (1994).
Following A. Ya. Aleksandrov and Yu. L. Solov’ev [Spatial problems of elasticity theory, Moscow, Nauka (1978)], the authors discuss the following boundary value problem for the generalized analytic functions: find \(\Phi_k\), \(\Psi_k\) analytic in the half-plane \(D_k\) \((k=1,2)\), \(\partial D_1=\Gamma=\partial D_2\), \(D_1\cup\Gamma\cup D_2=\) complex plane, \(\Gamma\) is the real axis, with the boundary conditions \(\Phi_k(t)- \overline{\Psi_k(t)}= f_k(t)\), \(t\in L\), \(a_1\Phi_1(t)= b_1\overline{\Psi_1(t)}+ c_1\Phi_2(t)\), \(a_2\Psi_1(t)= b_2 \overline{\Phi_1(t)}+ c_2\Psi_2(t)\), \(t\in\Gamma\setminus L\), where \(a_k,b_k,c_k\) are given constants, and \(f_k(t)\) is a given function. The problem is reduced to a singular integral equation.
