Линейное проективное инд-многообразие X называется 2-связным, если всякая точка из X лежит на проективной прямой в X, и для любых двух прямых l и l 0 из X существует цепочка прямых l = l1, l2, ..., lk = l 0 , такая, что любая пара (li , li+1) содержится в проективной плоскости P 2 , принадлежащей X. В данной работе изучается линейное инд-многообразие X, являющееся полным пересечением в линейном инд-грассманиане G = lim−→G(km, nm). По опре- делению X – это пересечение G с конечным числом инд-гиперповерхностей Yi = lim−→Yi,m, m ≥ 1, фиксированных степеней di , i = 1, ..., l, в пространстве P∞, в которое инд-грассманиан G вложен по Плюккеру. Из работы [<xref ref-type="bibr" rid="cit17">17</xref>] вытекает, что X 1-связно. Обобщая этот результат, в данной работе мы доказываем, что X 2-связно. Из этого свойства выводится, что всякое векторное расслоение E конечного ранга на X является равномерным, то есть ограничение расслоения E на все проективные прямые в X имеет одинаковый тип расщепления. Мотивация данной работы состоит в распространении теорем типа Барта– Ван де Вена–Тюрина–Сато на случай полных пересечений конечной коразмерности в инд-грассманианах.</p></abstract><trans-abstract xml:lang="en"><p>A linear projective ind-variety X is called 1-connected if any two points on it can be connected by a chain of lines l1, l2, ..., lk in X, such that li intersects li+1. A linear projective ind-variety X is called 2-connected if any point of X lies on a projective line in X and for any two lines l and l 0 in X there is a chain of lines l = l1, l2, ..., lk = l 0 , such that any pair (li , li+1) is contained in a projective plane P 2 in X. In this work we study an ind-variety X that is a complete intersection in the linear ind-Grassmannian G = lim−→G(km, nm). By definition, X is an intersection of G with a finite number of ind-hypersufaces Yi = lim−→Yi,m, m ≥ 1, of fixed degrees di , i = 1, ..., l, in the space P∞, in which the ind-Grassmannian G is embedded by Pl¨ucker. One can deduce from work [<xref ref-type="bibr" rid="cit17">17</xref>] that X is 1-connected. Generalising this result we prove that X is 2-connected. We deduce from this property that any vector bundle E of finite rank on X is uniform, i. e. the restriction of E to all projective lines in X has the same splitting type. The motiavtion of this work is to extend theorems of Barth - Van de Ven - Tjurin - Sato type to complete intersections of finite codimension in ind-Grassmannians.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инд-грассманиан</kwd><kwd>векторное расслоение</kwd><kwd>равномерное расслоение</kwd><kwd>многообразие Фано прямых</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ind-Grassmannian</kwd><kwd>vector bundle</kwd><kwd>uniform bundle</kwd><kwd>Fano variety of lines</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Altman A.
