Abstract:

In the paper, the max-mixed scheme and min-mixed scheme are proposed for the critical temperature and gap solution of Bogoliubov-Tolmachev-Shirkov model in superconductivity theory. For the first time, the numerical solutions of critical temperature and gap solution are given for the above model with the alternating kernel function. The convergence analysis of the numerical method is also given. Also, some numerical examples are presented to verify the results of the paper.
