Inflationary solutions for the models with the exponent and power law scale factor in the framework of the two-component chiral cosmological model are obtained. The special distribution between chiral fields, when one of them is responsible for the dynamics in the spatially-flat section and another - for the warping of this section, is suggested.</abstract><trans-abstract xml:lang="ru">В работе предложен новый метод построения точных решений для киральной космологической модели в пространственно-плоской, открытой и замкнутой Вселенной. Найдены инфляционные решения для моделей с экспоненциальным расширением и со степенным масштабным фактором в рамках двухкомпонентной киральной космологической модели. Предложено специальное распределение между киральными полями, когда одно из них ответственно за динамику в пространственно-плоском сечении, а другое - за искривление этого сечения.</trans-abstract><kwd-group xml:lang="en"><kwd>cosmology</kwd><kwd>inflation</kwd><kwd>non-linear sigma mode</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>космология</kwd><kwd>инфляция</kwd><kwd>нелинейная сигма модель</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Линде А.
