This is an announcement for the paper “Equivalence between almost-greedy bases and semi-greedy bases” by Pablo M. Berná<https://arxiv.org/search?searchtype=author&query=Bern%C3%A1%2C+P+M>. Abstract: In this paper we show that almost-greedy bases are equivalent to semi-greedy bases in the context of Schauder bases in Banach spaces. Moreover, using this result, we answer a question asked in [3]. The paper may be downloaded from the archive by web browser from URL https://arxiv.org/abs/1804.05730
