Stockholm Mathematics Centre Prizes for Excellent Doctoral Dissertation and Master Theses 2019/2020
Excellent Master Theses
Statistical Learning and Analysis on Homology-Based Features
Advisors: Martina Scolamiero and Wojciech Chacholski
Jens Agerberg is awarded the SMC prize for his excellent master thesis on statistical learning, where he combines topological data analysis with statistics, probability theory and machine learning. His thesis demonstrates great creativity and reveals new connections between kernel methods and stable ranks. Besides the theoretical results, Agerberg also illustrates the practical value of the methods by applying his findings to real datasets, one from the OASIS open access brain imaging dataset and another dataset collected from Reddit.

Local rigidity of some Lie group actions
Advisor: Danijela Damjanovic
Sven Sandfeldt is awarded the SMC prize for his excellent master thesis. His work deals with rigidity phenomena, a subject that has been studied extensively in dynamical systems, in the framework of connected Lie group actions. In his thesis, Sandfeldt clearly demonstrates a thorough understanding of a technically difficult area, and makes original contributions to an important branch of dynamical systems.

Statistical Aspects of Sustainability in Optimal Portfolio Theory
Advisor: Taras Bodnar
Vivi Wong is awarded the SMC prize for her excellent master thesis that investigates the performance of portfolios consisting of sustainable assets only. Based on optimal portfolio theory and ESG sustainability ratings, Wong discusses mean-variance spanning tests and their robustness in order to present a careful statistical analysis of data from the OMXS30 index of the Stockholm stock exchange, and finds no statistical justification for investing in assets considered non-sustainable.
