yes, - indeed there are some cases when people use cyrillic letters to
denote mathematical notions (objects), just like latin letters.

some examples are cyrillic variants of GCD (greatest common divisor)
and SCM (smallest common multiple) which are denoted with cyrillic
letters; projection operator in geometry (in russian literature);
people use cyrillic letters in mathematical formulae in some
non-strictly mathematician sciences (e.g. economics); there are some
stable usages of cyrillic letters in physical notations (in russian
texts). but there are also established cases when cyrillic letters are
used internationally in strictly mathematical publications -
e.g. Shafarevich groups in algebraic geometry are often denoted with
capital cyrillic letter sha - not only in russian literature!
