The most popular models dealing with dark energy are also discussed in short. We specially stretch on the spinor model of ﬂuid and dark energy. It is shown that the model with spinor ﬁeld can resolve a number of standing problems of modern cosmology. It is noted that the non-trivial non-diagonal components of energy momentum tensor of spinor ﬁelds impose some severe restriction on the metric functions.</abstract><trans-abstract xml:lang="ru">В настоящем обзоре обсуждаются некоторые злободневные проблемы современной космологии. Также кратко обсуждаются наиболее популярные модели, использующие темную энергию. Показывается, что модель со спинорным полем может разрешить ряд первоочередных задач современной космологии. Отмечается, что нетривиальность недиагональных компонент тензора энергии-импульса спинорных полей накладывает некоторые сильные ограничения на метрические функции.</trans-abstract><kwd-group xml:lang="en"><kwd>Bianchi type cosmological models</kwd><kwd>Energy momentum tensor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>космологические модели типа Бианки</kwd><kwd>тензор энергии–импульса</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Henneaux M.
