% Stylish file of the journal `` Trudy Instituta Matematiki i Mekhaniki UrO RAN '' (Vol. 24, No.1, 2018).

% By default - single numbering for environments (theorems, lemmas, sentences, etc.),
% Double for formulas.
% If necessary, you can change the type of numbering.
% After zeroing the "equation" counter at the beginning of each section
% Follow yourself, if necessary!
% Please follow the abbreviations of commands and environments.
% Stick to standard abbreviations for journal titles.
% The list of references  should be ordered either alphabetically or in the order in which they are referred to in the paper.
