6. Canonical Bases for Algebraic Computations
Sammanfattning : This thesis deals with computational methods in algebra, mainly focusing on the concept of Gröbner and SAGBI bases in non-commutative algebras. The material has a natural division into two parts. The first part is a rather extensive treatment of the basic theory of Gröbner bases and SAGBI bases in the non-commutative polynomial ring. LÄS MER
7. Formal Languages and Automata in Computational Algebra
Sammanfattning : This thesis is a collection of six papers in computational algebra. In particular, we study noncommutative Gröb- ner bases, SAGBI bases and similar algebraic objects which can be represented as a graph or an automaton. LÄS MER
8. New Results on Triangulation, Polynomial Equation Solving and Their Application in Global Localization
Sammanfattning : This thesis addresses the problem of global localization from images. The overall goal is to find the location and the direction of a camera given an image taken with the camera relative a 3D world model. In order to solve the problem several subproblems have to be handled. LÄS MER
9. Algebraic Methods for Verification and Control of Discrete Event Dynamic Systems
Sammanfattning : Discrete event dynamic systems (DEDS) have become increasingly important in industry and there is a need for structured methods applicable to the design process of DEDS. In this thesis we consider algebraic methods for verification and control of DEDS.To model DEDS we use polynomials in a quotient ring. LÄS MER
10. Topological and geometrical methods in data analysis
Sammanfattning : This thesis concerns two related data analysis pipelines, using topological and geometrical methods respectively, to extract relevant information. The first pipeline, referred to as the topological data analysis (TDA) pipeline, constructs a filtered simplicial complex on a given data set in order to describe its shape. LÄS MER
