Research Interest
I am interested in different aspects of the mathematical concepts of Quantum Field Theory. These include:
Poisson Sigma Model / Deformation Quantization, (Cyclic) Formality,
Relational Symplectic Groupoids,
AKSZ Sigma Models and (Quantum) Globalization Constructions,
Elements of Formal Geometry,
Chern-Simons Theory / Reshetikhin-Turaev, Turaev-Viro Construction,
Floer Theory, Invariants of 3-Manifolds,
Batalin-Vilkovisky (BV) Gauge Formalism for Manifolds with Boundary (BV-BFV), Equivariant BV Formalism,
Higher Codimension Quantization (e.g. Manifolds with Corners),
Elements of String Theory,
Twisted Supersymmetric Field Theories, A- and B-Models,
Mathematical Aspects of the Holography Principle (Boundary Theories, AdS/CFT Correspondence),
Topological Invariants of 4-Manifolds (Supersymmetric Yang-Mills Theory, Seiberg-Witten Theory, Donaldson-Witten Theory, Nekrasov Theory),
Aspects of Symplectic Topology (Fukaya categories, Homological Mirror Symmetry),
Derived Algebraic Geometry and its Connection to QFT,
Concepts of Representation Theory and Quantum Groups,
Higher Gauge Theory Methods, Donaldson-Thomas Theory.
