HOPEGA is a research program at the Department of Mathematics of the Aristotle University of Thessaloniki (AUTh) that focuses on homotopy theory and its applications to geometry and algebra. Its research activities span a range of areas, including: algebraic K-theory, higher categories, cut-and-paste K-theory of manifolds, cobordism categories, bivariant theories, higher derivators, simplicial volume, bounded cohomology, homological methods in functional analysis,... 

HOPEGA started in October 2025 and is funded by the Hellenic Foundation for Research and Innovation (HFRI) for four years.
