  1. 1. On one-dimensional dynamical systems and commuting elements in non-commutative algebras

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Alex Behakanira Tumwesigye; Mälardalens högskola.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Commutativity; dynamical systems; commutant; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : This thesis work is about commutativity which is a very important topic in mathematics, physics, engineering and many other fields. Two processes are said to be commutative if the order of "operation" of these processes does not matter. LÄS MER

  2. 2. Crossed Product Structures Associated with Topological Dynamical Systems

    Detta är en avhandling från Centre for Mathematical Sciences, Lund University

    Författare :Christian Svensson; Lunds universitet.; Lund University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; maximal abelian subalgebra; commutant; C*-algebra; dynamical system; ideal; Banach algebra; Crossed product;

    Sammanfattning : We study connections between topological dynamical systems and associated algebras of crossed product type. We derive equivalences between structural properties of a crossed product and dynamical properties of the associated system and furthermore derive qualitative results concerning the crossed product that are true regardless of the corresponding dynamical system.

  3. 3. Dynamical Systems and Commutants in Non-Commutative Algebras

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Alex Behakanira Tumwesigye; Mälardalens högskola.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : This thesis work is about commutativity which is a very important topic in Mathematics, Physics, Engineering and many other fields. In Mathematics, it is well known that matrix multiplication (or composition of linear operators on a finite dimensional vector space) is not always commutative. LÄS MER

  4. 4. Ideals and Maximal Commutative Subrings of Graded Rings

    Detta är en avhandling från Centre for Mathematical Sciences, Lund University

    Författare :Johan Öinert; Lunds universitet.; Lund University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ideals; simple rings; maximal commutativity; Crossed products; graded rings;

    Sammanfattning : This thesis is mainly concerned with the intersection between ideals and (maximal commutative) subrings of graded rings. The motivation for this investigation originates in the theory of C*-crossed product algebras associated to topological dynamical systems, where connections between intersection properties of ideals and maximal commutativity of certain subalgebras are well-known.
