Markushevich's ill-posed boundary-value problem for multiply connected domains with circular boundaries
I. Kh. Sabitov M. V. Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
We consider a little-known boundary-value problem of linear conjugation in
the theory of functions of a complex variable in multiply connected domains.
Although it was posed in a general form by Markushevich in 1946 and used
in Vekua's geometric studies, it is still poorly understood. The problem
is ill-posed: it loses solubility after arbitrarily small perturbations
of the coefficient. Under certain simple conditions, we solve the problem
completely by establishing necessary and sufficient criteria for its solubility
and giving a construction for its solutions.
Keywords:
holomorphic and meromorphic functions, linear conjugation problem,
ill-posedness of a problem, index, solubility conditions.
