1. Hopf Invariants in Real and Rational Homotopy Theory
University dissertation from Stockholm : Department of Mathematics, Stockholm UniversityAbstract : In this thesis we use the theory of algebraic operads to define a complete invariant of real and rational homotopy classes of maps of topological spaces and manifolds. More precisely let f,g : M > N be two smooth maps between manifolds M and N. READ MORE

2. Hopf and Frobenius algebras in conformal field theory
University dissertation from Karlstad : Karlstad University PressAbstract : There are several reasons to be interested in conformal field theories in two dimensions. Apart from arising in various physical applications, ranging from statistical mechanics to string theory, conformal field theory is a class of quantum field theories that is interesting on its own. First of all there is a large amount of symmetries. READ MORE

3. Irreducible Representations of Quantum Affine Algebras
University dissertation from Karlstad : Karlstad University PressAbstract : We construct finitedimensional representations of the quantum affine algebra associated to the simple finitedimensional Lie algebra sl(n+1). The module structure is defined on the vector space tensor product of the fundamental representations of the quantum affine algebra. READ MORE

4. Heat loss to the ground from a building : slab on the ground and cellar
University dissertation from Byggnadsfysik LTH, Lunds Tekniska HögskolaAbstract : Heated buildings induce a heat flow from the building foundation into the ground. The topic of this thesis is the thermal process in the ground and, in particular, the heat losses from the building to the ground. Foundations of the three types slab on the ground, cellar, and crawlspace are dealt with. The crawlspace is treated in separate report. READ MORE

5. TwoBarrier Problems in Applied Probability: Algorithms and Analysis
University dissertation from Centre for Mathematical Sciences, Lund UniversityAbstract : This thesis consists of five papers (AE). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x0. We define the loss rate due to the reflection. READ MORE
