Integral geometry methods on deformed categories to geometrical Langlands ramifications in field theory. (English) Zbl 1317.53115
Summary: Some derived categories and their deformed versions are used to develop a theory of the ramifications of fields studied in the geometrical Langlands program to obtain the correspondences between moduli stacks and solution classes represented cohomologically under integral geometry methods, more specific, under use of the Penrose transform framework. The presented work proposes the derived categories in geometrical Langlands ramifications problem as a special characterization of the ramified fields whose ramifications can be identified as degenerated cycles corresponding to orbits of twisted \(\mathcal D\)-modules of a certain moduli space that can be induced by an appropriate Zuckerman functor obtained by a generalized Penrose transform developed on derived categories of the moduli space \(\mathcal{M}_{Flat}(G, C)\), obtaining classes of objects in a moduli space \(\mathcal M_{Higgs}(G, C)\). Using induced cohomology on generalized \(G\)-modules generalized versions of Verma modules are identified corresponding to three categories that have been identified as classes of a Hecke category \(\mathcal H_{G^{\wedge},\infty}\), and that classify the three type solutions in the field theory.
