On the extremization of some functionals in a problem on nonoverlapping regions

A.K. Bakhtin. Scientific legacy

“…In 1975, in accordance with this idea, G. P. Bakhtina [23] in her thesis first considered and solved a number of extremal problems on the class of mutually non-overlapping domains with so-called "free" poles of quadratic differentials.…”

Extreme problem for a mosaic system of points on the open sets and nonoverlapping domains

“…In 1974, P. Tamrazov advanced the idea of the consideration of extreme problems, where the poles of quadratic differentials have a certain freedom (see [13]). In the frame of this idea, G. Bakhtina formulated a number of problems with the so-called "free poles" on the unit circle (see, e.g., [6]).…”
