We consider the problem of obtaining asymptotics for solutions of differential operators in a neighborhood of an irregular singular point; more precisely, the construction of uniform asymptotics for solutions of linear differential equations with second-order meromorphic coefficients in a neighborhood of a singular point. Examples are also given that confirm the relevance of the results obtained in the theory of equations of mathematical physics.
Keywords: Second-order differential operator, singular points.
Mots-clés : meromorphic coefficients
