چکیده
We find a general expression for the free energy of G(φ) = φ2k generalized 2D YangMills theories in the strong (A > Ac) region at large N . We also show that in this region, the density function of Young tableau of these models is a three-cut problem. In the specific φ6 model, we show that the theory has a third order phase transition, like φ2 (YM2) and φ 4 models. We have some comments for k ≥ 4 cases. At the end, we study the phase structure of φ2 + gφ4 model for g ≤ A4 region. e-mail:[email protected] e-mail:[email protected]

Large-N behavior of the Wilson loops of generalized two-dimensional Yang-Mills theories
The large-N limit of the expectation values of the Wilson loops in the fundamental representation, corresponding to two-dimensional U(N) YangMills and generalized Yang-Mills theories on a sphere are studied. The behavior of the expectation values of the Wilson loops both near the critical area and for large areas are investigated. It is shown that the expectation values of the Wilson loops at l...
متن کاملNon-Douglas-Kazakov phase transition of two-dimensional generalized Yang-Mills theories
In two-dimensional Yang-Mills and generalized Yang-Mills theories for large gauge groups, there is a dominant representation determining the thermodynamic limit of the system. This representation is characterized by a density the value of which should everywhere be between zero and one. This density itself is determined through a saddle-point analysis. For some values of the parameter space, th...
متن کاملPhase transitions of Large-N two-dimensional Yang-Mills and generalized Yang-Mills theories in the double scaling limit
The large-N behavior of Yang-Mills and generalized Yang-Mills theories in the double-scaling limit is investigated. By the double-scaling limit, it is meant that the area of the manifold on which the theory is defined, is itself a function of N . It is shown that phase transitions of different orders occur, depending on the functional dependence of the area on N . The finite-size scalings of th...
متن کاملAn Introduction to Generalized Yang-Mills Theories
In generalized Yang-Mills theories scalar fields can be gauged just as vector fields in a usual Yang-Mills theory, albeit it is done in the spinorial representation. The presentation of these theories is aesthetic in the following sense: A physical theory using Yang-Mills theories requires several terms and irreducible representations, but with generalized Yang-Mills theories, only two terms an...
متن کاملYang-mills, Complex Structures and Chern’s Last Theorem
Recently Shiing-Shen Chern suggested that the six dimensional sphere S has no complex structure. Here we explore the relations between his arguments and Yang-Mills theories. In particular, we propose that Chern’s approach is widely applicable to investigate connections between the geometry of manifolds and the structure of gauge theories. We also discuss several examples of manifolds, both with...
