Department of Mathematics and Systems Analysis

Department of Mathematics and Systems Analysis

The five main research areas of the Department are: analysis; discrete mathematics; applied mathematics and mechanics; stochastics and statistics; systems analysis and operations research. We offer major and minor studies at the bachelor's and master's level and provide doctoral research training. Our graduates have been recruited by universities, research institutes, governmental agencies as well as companies in the financial, energy and transportation sectors, for instance.

Research

Defence of dissertation in the field of mathematics, Helle Majander 11.11.2016

29. November 2016

 

 

Helle Majander, M.Sc., will defend the dissertation "Efficient reconstruction algorithms for three-dimensional tomographic imaging" on 11 November 2016 at 12 noon in Aalto University School of Science, lecture hall 1, Otakaari 1, Espoo. In the dissertation, we study the iterative algorithms for solving the inverse problems related to tomographic imaging. We present an efficient algorithm that can be used with different imaging modalities and we study the compensation of geometric modeling errors in particular for electrical impedance tomography.

Associate Professor Kim Knudsen, Technical University of Denmark, will act as the opponent. Custos is Professor Nuutti Hyvönen, Department of Mathematics and Systems Analysis. Dissertation release is available in Finnish at: http://sci.aalto.fi/en/current/events/vaitos_majander_helle/.

Research

Defence of dissertation in the field of mathematics, Janne Korvenpää, M.Sc. (Tech.), 18.11.2016

29. November 2016

Janne Korvenpää, M.Sc. (Tech.), will defend the dissertation "Nonlocal nonlinear potential theory and fractional integral operators" on 18 November 2016 at 12 noon in Aalto University School of Science, lecture hall M1, Otakaari 1, Espoo. In the dissertation, potential theory for fractional Laplace type equations is developed. These equations are nonlocal integro-differential equations having many similarities with typical partial differential equations.

Professor Lorenzo Brasco, University of Ferrara, will act as the opponent. Custos is Professor Juha Kinnunen, Department of Mathematics and Systems Analysis. Dissertation release is available in Finnish at: http://sci.aalto.fi/en/current/events/vaitos_korvenpaa_janne/

Research

Defence of dissertation in the field of systems and operations research, Jussi Kangaspunta, M.Sc. (Tech.), 4.11.2016

29. November 2016

 

 

Jussi Kangaspunta, M.Sc. (Tech.), will defend the dissertation "Resource Allocation Methods for Defence and Infrastructure Systems" on 4 November 2016 at 12 noon in Aalto University School of Science, lecture hall H304, Otakaari 1, Espoo. In this dissertation, methods to support the allocation of resources to investment alternatives are studied and developed. These methods have been illustrated by examining problems from defence planning and critical infrastructure risk management.

Professor Vicki Bier, University of Wisconsin-Madison, will act as opponent. Custos is professor Ahti Salo, Department of Mathematics and Systems Analysis. Dissertation release is available in Finnish at: http://sci.aalto.fi/en/current/events/vaitos_kangaspunta_jussi/.
