The conjecture on acyclic 5-choosability of planar graphs [Borodin et al., 2002] as yet has been verified only for several restricted classes of graphs. None of these classes allows 4-cycles. We prove that a planar graph is acyclically 5-choosable if it does not contain an i-cycle adjacent to a j-cy

## Abstract A proper vertex coloring of a graph __G__=(__V, E__) is acyclic if __G__ contains no bicolored cycle. A graph __G__ is acyclically __L__‐list colorable if for a given list assignment __L__={__L__(__v__)|__v__∈__V__}, there exists a proper acyclic coloring Ο€ of __G__ such that Ο€(__v__)∈_
