ALTA is a research unit within the Department of Mathematics and Computer Science (FB3) at the University of Bremen. According to university statutes it has the legal status of an Institute.

Our main focus is pure and applied research in algebra, geometry, topology, discrete mathematics, and theoretical computer science. The majority of our work is motivated by applications in exact sciences or industry. Current applications include distributed computing, physics, bioinformatics, and data analysis. Further details can be found on the projects page.
