چکیده
The aim of this report is to provide a brief account of the mathematics underlying a substatial part of modern theoretical physics, more specifically field theory, and in particular the gauge theories used to describe elementary particle interactions. Therefore, the elements of mathematics we consider mainly belong to the realms of differential geometry and topology, and is divided into five main chapters; Manifolds, Tensors, Differential Forms, Lie Theory and Bundles and Gauge Theory. Each chapter serve as an elementary introduction to the subject it concerns and the degree of depth is largely determined by what is optimal with respect to comprehension of the other chapters. Sammanfattning. Syftet med denna rapport är att kort redogöra för matematiken som ligger till grund för en väsentlig del av den moderna teoretiska fysiken, mer specifikt fältteori och speciellt gaugeteorierna som används för att beskriva elementarpartikelväxelverkan. Matematiken vi behandlar tillhör därför i huvudsak omr̊adena differentialgeometri och topologi och är uppdelad i fem huvudkapitel; m̊angfalder, tensorer, differentialformer, lieteori och buntar och gaugeteori. Varje kapitel utgör en elementär introduktion till omr̊adet det rör och framställningens djup beror i huvudsak p̊a vad som är optimalt med avseende p̊a först̊aelse av de övriga kapitlen.

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...
متن کاملNon-String Pursuit towards Unified Model on the Lattice
Non-standard overview on the possible formulation towards a unified model on the lattice is presented. It is based on the generalized gauge theory which is formulated by differential forms and thus expected to fit in a simplicial manifold. We first review suggestive known results towards this direction. As a small step of concrete realization of the program, we propose a lattice Chern-Simons gr...
متن کاملOn the Landau Ginzburg theory of MAG projected SU ( 2 ) lattice gauge theory
Maximal Abelian gauge fixing and subsequent Abelian projection of SU(2) lattice gauge theory defines closed trajectories of magnetic monopoles. These trajectories can be interpreted in terms of an effective scalar field theory of the MAG monopoles using the worldline representation of the functional determinants. Employing the monopole worldlines detected in the numerical simulation, we show th...

متن کاملTowards a Many - Body Treatment of Hamiltonian Lattice SU ( N ) Gauge Theory
We develop a consistent approach to Hamiltonian lattice gauge theory, using the maximal-tree gauge. The various constraints are discussed and implemented. An independent and complete set of variables for the colourless sector is determined. A general scheme to construct the eigenstates of the electric energy operator using a symbolic method is described. It is shown how the one-plaquette proble...
