Application of Function Convexity in Proving Divergence of Series
-
Abstract: For the convergence and divergence of series, based on the definition of convergence and divergence of series, combined with the convexity of general term functions, the sufficient conditions for the divergence of series were given when functions were upper convex or lower convex, and an example was given for application.
