On Singular Singularly-Perturbed Initial Value Problems.

Abstract

Consider the vector initial value problem epsilon y = f(t,y,epsilon), y(0) = y superscript 0 (epsilon) with f(t,y,0) = F(t)y + G(t) for a singular matrix F(t) of constant rank with stable eigenvalues and zero eigenvalues having simple elementary divisors. This paper shows how to determine the unique limiting solution when the reduced problem F Y sub 0 + G = 0 is solvable and how to obtain a uniform asymptotic expansion for the solution on finite t intervals.
