Configurations of fivebranes, twobranes and fourbranes in type IIA string theory, which give (1 + 1) dimensional supersymmetric gauge theories in the low energy limit, are constructed. It is shown that these brane configurations are equivalent to a certain class of matrix string theories. This opens up an avenue for the investigation of matrix string dynamics via the geometry of brane configurations in type IIA string theory. (C) 1998 Elsevier Science B.V. All rights reserved.
