2. 1. Ideals and Maximal Commutative Subrings of Graded Rings

   Author : Johan Öinert; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ideals; simple rings; maximal commutativity; Crossed products; graded rings;

   Abstract : 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.

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

   Author : Alex Behakanira Tumwesigye; Sergei Silvestrov; Johan Richter; Linus Carlsson; Viktor Abramov; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Commutativity; dynamical systems; commutant; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Abstract : 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. READ MORE

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

   Author : Alex Behakanira Tumwesigye; Sergei Silvestrov; Johan Richter; Linus Carlsson; Olga Liivapuu; Mälardalens högskola; []
   Keywords : Mathematics Applied Mathematics; matematik tillämpad matematik;

   Abstract : 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. READ MORE
