摘要：

The extension problem for rectangular matrices with values in Banach algebra to an invertible square matrix is investigated. For this problem to be solvable for a matrix D , the following condition is necessary: for every maximal ideal m of the algebra, the numerical matrix D(m) must have maximal rank. This condition is sufficient for many algebras, for example, for the algebras H(infinity)(R) of bounded analytic functions in a plane finitely connected domain R and to Sarason subalgebras in the algebra H(infinity).
