Abstract:Let X be a topological space and let F be a filter on N, recall that a sequence (xn)nN in X is said to be F-convergent to the point xX, if for each neighborhood U of x, {nN:xnU}∈F. By using F-convergence in ?1 and in Banach spaces, we characterize the P-filters, the P-filters+, the weak P-filters, the Q-filters, the Q-filters+, the weak Q-filters, the selective filters and the selective+ filters.
