摘要: Abstract Asymptotic expansions are of great interest and significance in the study canard explosions singularly perturbed systems. Several classical methods have been developed to compute such expansions. However, for non-generic case considered this letter, those fail do so. There only exists an estimation on first non-zero term literature. Our aim is propose a new approach find asymptotic iteratively. Moreover, exact value provided terms Airy function. The numerical results validate our analytical approximations.
