The paper deals with the system of linear difference equations in Rd with the
right part switched by homogeneous ergodic Markov chain {yt } on the compact
phase space Y. We prove that there exists such the linear continuous operator A on the
space of symmetric d xd-matrix-function q(y) that for any t =1,2,..., y, and
x one can write the equality E{(q(yt)xt; xt) /y0 = y; x0 = x} = E{(Atq)(y)x; x)}.
This approach permits to derive such the basis matrix B(y) in the space Rd that the random
process zt = B(yt)xt has the same mean square Lyapunov exponents as the solution of the
above equation x(t) and to propose convenient to application algorithm for asymptotic
analysis of the equations with near to constant coefficients.
