Abstract:
We prove that, for any admissible sequence, the corresponding general
Franklin system $\{f_n(x)\}_{n=0}^{\infty}$ possesses the following
property. A series $\sum_{n=0}^{\infty}a_nf_n(x)$ is absolutely convergent
almost everywhere on a set $E$ if and only if it is unconditionally
convergent almost everywhere on $E$.
Keywords:series, general Franklin system, absolute convergence, unconditional convergence.
