On Relevance Of Matrix Coordinates For The Inside Of Baryons
  It is argued that one natural choice for coordinates of constituents of a baryonic state in a SU(N) gauge theory are N x N hermitian matrices. It is discussed that the relevance of matrix coordinates is supported at least by the restricted form of the color symmetry. Based on the previous investigations in this direction, the consequences of the idea are shortly reviewed. The model has been considered is originated by the D0-branes of String Theory.
