On the principle of length and area for plane mappings with a limited distortion (Q1377972)

The title of the paper being reviewed tells almost everything about its contents. The author presents an interesting generalization of the fundamental inequality which is known in the literature as the principle of length and area [cf. e.g. \textit{G. D. Suvorov}, The generalized length and area principle in mapping theory (1985; Zbl 0669.30012)] and has numerous applications in function theory [cf. e.g. \textit{Yu. G. Reshetnyak}, Spatial mappings with bounded distortion (1982; Zbl 0487.30011)].
