Об интегральной характеризации некоторых обобщений квазирегулярных отображений и значений условия расходимости интеграла в геометрической теории функций

The paper deals with the theory of space mappings. For a generalization of quasiregular mappings important
for the investigation of the Sobolev and other known classes of mappings, we propose a simple
condition satisfied by all mappings of this kind and only by these mappings. On the basis of conditions
of divergence of the integrals, we establish sufficient conditions for the normality of the families of the
analyzed classes of mappings and solve the problem of removing isolated singularities. Some applications
of the obtained results to mappings from the Sobolev class are discussed.
