Russ. Acad. Sci., Dokl., Math. 50, No. 1, 104-107 (1995); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 337, No. 4, 447-449 (1994).
The Dirichlet problem is studied for a second-order elliptic equation with incompatible degeneration of initial data in an arbitrary convex domain $$\Omega$$; the existence and uniqueness of an $$R_\nu$$-generalized solution in the weighted space $$W^1_{2, \nu+ \beta/2}(\Omega^*)$$ are established, where $$\Omega^*$$ is a subdomain of $$\Omega$$ on which a certain condition on the coefficients holds. The existence of an $$R_\nu$$-generalized solution in $$W^1_{2, \nu+ \beta/2}(\Omega)$$ is proved, and estimates of the solution are obtained in terms of the norm in $${\mathcal L}_{2, \mu}$$ of the right-side of the equation.
