ENTROPY OF A SEMI-FLOW FOR RECURRENCE TIME
Based on the theory of Carathéodory, we introduce entropy and multifractal spectrum associated with Poincaré recurrences for a semi-flow. Moreover, an exact formula on multifractal spectrum of local entropies of a semi-flow for recurrence time is established.
