We must therefore show that the equations X-T2X 0 and x-T;x 0 have the same number of independent solutions.
Basic Concepts Roughly speaking, a partial differential equation of order k is an equation of the form F(x, U, 8 1u,., 8"u, 8u,., 8u) 0 relating a function u of the variable easeus data recovery wizard serial number x E jR" and its derivatives of order.
Since To has finite rank, so does.
