Title: Almost Subadditive Extensions of Kingman's Ergodic Theorem
Abstract: Based on two notions of almost subadditivity which were introduced by
Derriennic[1] and Schürger[6], two a.s. limit theorems are proved which both
generalize Kingman's[2] subadditive ergodic theorem. These results, being
valid under weak moment conditions, are obtained by short proofs. One of
these proofs is completely elementary and does not even make use of
Birkhoff's ergodic theorem which, instead, is obtained as a byproduct.
Keywords: Subadditive processes, ergodic theory, almost subadditive process,
entropy
