The Engström group
Our research is focused on combinatorial problems connected to commutative algebra, algebraic geometry and topology. Some questions are motivated by applications in for example biology, computer science and physics.
We are in charge of the courses in Algebraic Geometry and Graph Theory. The master level course MS-E1050 Graph Theory is taught every year in period I, in fall 2021 by Ragnar Freij (SISU, MyCourses). Every second year the master level courses MS-E1143 Algebraic Geometry I is in period I (SISU, MyCourses) and MS-E1144 Algebraic Geometry II is in period II (SISU, MyCourses). In fall 2021 they are taught by Alexander Engström. (The old course codes MS-E1140 and MS-E1141 are not valid)
