PY - 2001/12/01 Y2 - 2024/03/28 TI - Almost-periodicity problem as a fixed-point problem for evolution inclusions JF - Topological Methods in Nonlinear Analysis JA - TMNA VL - 18 IS - 2 SE - DO - UR - https://apcz.umk.pl/TMNA/article/view/TMNA.2001.038 SP - 337 - 349 AB - Existence of almost-periodic solutions to quasi-linear evolutioninclusions under a Stepanov almost-periodic forcing isnontraditionally examined by means of the Banach-like and theSchauder-Tikhonov-like fixed-point theorems. These multivaluedfixed-point principles concern condensing operators inalmost-periodic function spaces or their suitable closed subsets.The Bohr-Neugebauer-type theorem jointly with the Bochnertransform are employed, besides another, for this purpose.Obstructions related to possible generalizations are discussed.
