26. Algorithms in data mining : reduced rank regression and classification by tensor methods
Sammanfattning : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. LÄS MER
27. Introduction to Data Tensor Models for Social Science
Sammanfattning : .... LÄS MER
28. Extensions of general relativity : scalar tensor theory, topology of space-time and supergravity
Sammanfattning : This report together with Papers 1—11 constitute a dissertation on the subjects of Scalar Tensor Theories, Topology of Space-Time and Supergravity. These three areas are briefly introduced for providing a background to the work in 1—11. A general discussion of motivations for modifications of the Einstein theory is also offered. . LÄS MER
29. On the Clebsch-Gordan problem for quiver representations
Sammanfattning : On the category of representations of a given quiver we define a tensor product point-wise and arrow-wise. The corresponding Clebsch-Gordan problem of how the tensor product of indecomposable representations decomposes into a direct sum of indecomposable representations is the topic of this thesis.

30. Conformal Einstein spaces and Bach tensor generalization in n dimensions
Sammanfattning : In this thesis we investigate necessary and su±cient conditions for an n-dimensional space, n ≥ 4, to be locally conformal to an Einstein space. After reviewing the classical results derived in tensors we consider the four-dimensional spinor result of Kozameh, Newman and Tod. LÄS MER
