Abstract:
In this paper a.s. convergence of Banach space valued $L_q$-mixingale sequences is proved. The result is used to establish a strong law of large numbers for Banach space valued $L_q$-mixingale sequences which has not been established previously. Conversely, $q$-smoothable Banach spaces are characterized in terms of strong laws of large numbers for these sequences.
Keywords:a.s. convergence, strong law of large numbers, Banach space valued $L_q$-mixingale sequences, smoothness of Banach space.
