An alternative strategy is to derive an approximate solution. In fact, asymptotic and perturbation methods employ the presence of a small parameter in the problem, e.g., a small coefficient in the ...
This measurement has profound effects on the production of radioactive lead (²⁰⁵Pb) in asymptotic giant branch (AGB) stars ...
Most mathematical models do not admit exact solutions. Asymptotic and perturbation methods provide powerful techniques for obtaining approximate solutions, which allow one to draw physical conclusions ...
Trajectories in a complex impact parameter plane are discussed, and it stresses the importance of the analytical properties of the phase shift function in this complex impact plane in the asymptotic ...
