abstract = {<p style="text-align: justify;">This paper investigates the problem of singular perturbed integral
initial values and Robin boundary values in the critical case. Based on the
boundary layer function method, we not only construct the asymptotic approximation of the original equation, but also prove the uniform validity of
the asymptotic solution by successive approximation. At the same time, we
give an example to prove the validity of the theoretical results.</p>},
