Formal Method for Finding Asymptotic Approximations
Kostadin G. Sheiretsky, Svetlin I. Antonov · 2021
A method is presented in which, through formal procedures, we can find the desired approximation in the decomposition of functions, differential equations and integral equations into asymptotic series. With this method we get only the approximation we are interested in. An “asymptotic bracket” has been introduced, the rules by which it is used have been defined and specific examples of its application have been given.
