The modified method of boundary functions constructed full, uniform asymptotic expansion of the solution bisingular Robin problem for a second order ordinary differential equations with turning points in the real axis. Constructed uniform asymptotic expansion of the solution of the Robin problem justified by the principle of maximum.
Keywords: asymptotic expansion, bisingularly problem, Robin problem, small parameter, boundary function.
