Institute of Mathematics and Computer Science

Currently, 12 professors, 29 other scientific members of staff and about 200 students work at our institute. There is a general atmosphere of cooperation between all groups. Professors and tutors are accessible at all times and students have the opportunity to actively take part in shaping their studies.

Our institute offers the subject Biomathematics (B.Sc. and M.Sc.) which is unique to Germany and the subject Mathematics (B.Sc., also with Computer Science, and M.Sc.). What is Biomathematics (article from the journal "Forschung und Lehre", Heft 6, 2015)? Biomathematicians are educated to be specialists in interdisciplinary cooperation and mathematicians to be experts for complex interrelationships. Both profiles are highly appreciated on the labour market. 

Two new subjects were introduced for winter semester 2016/17: B.Sc. in Mathematics and a teaching qualification "Mathematics at Secondary Schools".

Furthermore, students of other faculties, who minor in Mathematics, Statistics and Computer Science, are educated at our institute. Top-performing students of our institute contribute to the teaching as tutors. 

One key field of research is Biomathematics. Other fields of research are Quantum Stochastics, Differential Operators of Manifolds, Fractals and Time Series Analysis, Computability and Complexity Theory and Optimal Control. The complete names of the chairs and their areas of research are described on the pages of the professors and their employees.



Using invariants for coalescent-based phylogenetic inference

Prof. Dr. Laura Kubatko (The Ohio State University)


The advent of rapid and inexpensive DNA sequencing technologies has necessitated the development of computationally efficient methods for analyzing sequence data for many genes simultaneously in an evolutionary framework.  The coalescent process is the most commonly used model for linking the underlying genealogies of individual genes with the global species-level phylogenetic tree, but inference under the coalescent model is computationally daunting in the typical inference frameworks (e.g., the likelihood and Bayesian frameworks) due to the dimensionality of the space of both gene trees and species trees.   By viewing the data arising under the phylogenetic coalescent model as a collection of site patterns, the algebraic structure associated with the probability distribution on the site patterns can be used to develop computationally efficient methods for inference via phylogenetic invariants.  In this talk, I will describe how identifiability results for four-taxon species trees based on site pattern probabilities can be used to build a quartet-based inference algorithm for trees of arbitrary size.   I will demonstrate the performance of the method by applying it to both simulated and empirical data, and will compare it to competing methods.  Because the method is derived in a fully model-based framework (i.e., the coalescent process is used to model the relationship between gene trees and the species tree, and standard nucleotide substitution models (GTR+I+G and all submodels) are used for sequence-level evolution), these methods are promising approaches for computationally efficient, model-based inference for the large-scale sequence data available today.

Tag der Biomathematik

20 Jahre Biomathematik in Greifswald

Im Jahr 2018 feiert der Studiengang Biomathematik in Greifswald sein 20-jähriges Jubiläum, und gleichzeitig haben die European Mathematical Society und European Society for Mathematical and Theoretical Biology das Year of Mathematical Biology ausgerufen.

Aus diesem Anlass veranstalten wir einen Tag der Biomathematik in Greifswald und laden Studierende, Studieninteressierte, Alumni und alle, die Interesse an der Biomathematik haben, dazu herzlich ein.

1st Greifswald Summer School on Mathematics of Evolution

for PhD-students, PostDocs and advanced graduate students

As part of the Year of Mathematical Biology we proudly announce GreifOlution, the 1st Greifswald Summer School on Mathematics of Evolution (kindly funded by the DAAD, the German Academic Exchange Service).

The main focus of this summer school will be on mathematical models and methods for reconstructing phylogenetic trees and networks, but upon request we might also include some sessions on other related topics, e.g. from population genetics.

Erstsemesterwoche am Institut für Mathematik und Informatik

Vorbereitungskurs Mathematik

Unser Vorkurs ist für Studienanfängerinnen und Studienanfänger in den mathematischen Studiengängen (einschließlich Lehramt) vorgesehen. Der Kurs soll eine Brücke zwischen Lernen von Mathematik an der Schule und dem Mathematikstudium an der Universität bauen und damit den Studienbeginn erleichtern. Die Teilnahme ist freiwillig. Wir empfehlen aber den Besuch des Kurses, da erfahrungsgemäß bei vielen Abiturienten eine größere Lücke zwischen den an der Schule erworbenen und den an der Universität benötigten Kenntnissen und Fähigkeiten besteht.

Während des Kurses wollen wir mathematisches Denken trainieren und uns dabei mit folgenden Themen beschäftigen:

  • Logik und Beweistechniken
  • Mathematische Knobeleien
  • Mengenlehre, Kombinatorik
  • Elementare Zahlentheorie: Primzahlen und Chinesischer Restsatz
  • Komplexe Zahlen: Nullstellen von Polynomen
  • Elementare Funktionen
  • Folgen und Reihen: Grenzwerte
  • Gruppen und Geometrie: Platonische Körper
  • Graphentheorie: Einführung in die Evolutionsmathematik

Der Vorkurs findet vom 24.9.- 5.10.2018 statt. Täglich sind 4 – 5 Stunden Vorlesungen mit Übungen geplant. Die Auftaktveranstaltung findet am 24.9. um 8:15 Uhr im SR 4 in der Mehringstr. 48 statt. Eine Voranmeldung ist nicht unbedingt notwendig, für eine bessere Planung würden wir uns aber über eine Kontaktaufnahme über felipe.leitner(at)uni-greifswald(dot)de freuen.

Das Kolloquium ist eine gemeinsame Veranstaltung aller Arbeitsgruppen des Instituts für Mathematik und Informatik. Es findet in der Regel dreimal pro Semester statt. Das Kolloquium richtet sich an alle Mitglieder unseres Instituts, an Studierende in unseren Master-Studiengängen, an fortgeschrittene Studierende unserer Bachelor-Studiengänge, sowie an mathematisch interessierte Mitglieder anderer Institute der Mathematisch-Naturwissenschaftlichen Fakultät.

Alle interessierten Zuhörer sind immer herzlich willkommen.

The Colloquium is a regular event staged by all groups of the Institute of Mathematics and Computer Science. It usually takes place six times a year. It is addressed to all members of the faculty, postdocs, PhD students, master's students, and advanced bachelor's students, as well as colleagues from other institutes of the Faculty of Mathematics and Natural Sciences, who are interested in mathematics.

Everyone is welcome to attend our Colloquium.

Information for our speakers

Please let us know in advance which technical equipment you plan to use. We have rooms with large chalkboard, with a beamer, or both (also for simultaneous use).

The audience of your talk includes faculty and students of diverse mathematical backgrounds (pure & applied math, and computer science).

We kindly request that your talk be about 50 minutes in length, aimed at a general audience, and accessible to graduate students.

In particular, your talk should not be directed towards an audience of experts as is common in area-specific seminars. It is not necessary to present details on your latest research results. However, discussing their global meaning and consequences can be very valuable, and giving some historical perspective of your topic and explaining why it is of interest to you and your community can be an excellent start. Please do not feel obliged to explain all ideas in a fully rigorous way.

Indeed, most of the audience will very much appreciate a slightly informal approach to new topics and concepts.

We thank you very much in advance, and we are looking forward to your talk!
