Для этого класса при различных предположениях об электрическом поле изучаются условия на начальные данные, гарантирующие глобальное существование классического решения задачи Коши для заданного периода времени или разрушение решения за конечное время. Особое внимание уделено классу решений с осевой симметрией.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модель холодной плазмы</kwd><kwd>постоянное магнитное поле</kwd><kwd>постоянное электрическое поле</kwd><kwd>задача Коши</kwd><kwd>классическое решение</kwd><kwd>глобальная разрешимость</kwd><kwd>разрушение решения</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РНФ № 23-1100056 в Российском университете дружбы народов.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Розанова О.
