On Undecidable Dynamical Properties of Reversible One-Dimensional Cellular Automata
(Turku Centre for Computer Science, 2010-10-29)
Cellular automata are models for massively parallel computation. A cellular automaton consists of cells which are arranged in some kind of regular lattice and a local update rule which updates the state of each cell according ...
Class Field Theoretic Methods in the Design of Lattice Signal Constellations
(Turku Centre for Computer Science, 2008-04-16)
Subshifts with Simple Cellular Automata
(Turku Centre for Computer Science, 2014-06-28)
A subshift is a set of infinite one- or two-way sequences over a fixed finite set, defined by a set of forbidden patterns. In this thesis, we study subshifts in the topological setting, where the natural morphisms between ...
Generalized Orlicz spaces and partial differential equations with application to image restoration
(Turun yliopisto, 2022-11-11)
The research area of this thesis is nonlinear functional analysis, a branch of Mathematics which examines questions related to qualitative aspects of solution of a differential equation, such as existence, uniqueness, ...
Combinatorics of Pisot Substitutions
(Turku Centre for Computer Science, 2013-11-25)
On the computation of the class numbers of real Abelian fields
(Turku Centre for Computer Science, 2007-05-18)
On Inner Products Involving Holomorphic Cusp Forms and Maass Forms
(Turku Centre for Computer Science, 2009-10-30)
On Hyperbolic Type Metrics
(Suomalainen tiedeakatemia, 2009-03-20)
On Commutation and Conjugacy of Rational Languages and the Fixed Point Method
(Turku Centre for Computer Science, 2009-04-03)
The research on language equations has been active during last decades. Compared to the equations on words the equations on languages are much more difficult to solve. Even very simple equations that are easy to solve for ...
Structural and Computational Existence Results for Multidimensional Subshifts
(Turku Centre for Computer Science, 2015-07-31)
Symbolic dynamics is a branch of mathematics that studies the structure of infinite sequences of symbols, or in the multidimensional case, infinite grids of symbols. Classes of such sequences and grids defined by collections ...
