### On a problem of H.Bass for Chevalley groups of type E_7, by Eugene Plotkin

The paper is devoted to surjective stability of K_1-functor for
Chevalley groups of type E_7. This is a particular case of
stability problem for Chevalley groups. In the paper surjective
stability of K_1-functor is proved under natural conditions on
dimension of maximal spectrum of a ring and, independently, under
some special condition which is meaningful from the point of view of
equations defining a Chevalley group.
