Liouville/Toda central charges from M5-branes
نویسندگان
چکیده
We show that the central charge of the Liouville and ADE Toda theories can be reproduced by equivariantly integrating the anomaly eight-form of the corresponding six-dimensional N = (0, 2) theories, which describe the low-energy dynamics of M5-branes.

Para-Liouville/Toda central charges from M5-branes
We propose that N M5-branes, put on R/Zm with deformation parameters ǫ1,2, realize two-dimensional theory with ŜU(m)N symmetry and m-th para-WN symmetry. This includes the standard WN symmetry for m = 1 and super-Viraroro symmetry for m = N = 2. We provide a small check of this proposal by calculating the central charge of the 2d theory from the anomaly polynomial of the 6d theory. ∗on leave fr...
متن کامل2 00 6 Central charges of wrapped M 5 - brane backgrounds
We study the central charges of the supersymmetry algebra of branes in backgrounds corresponding to wrapped M5-branes. In the case of M5-branes wrapping a holomorphic 2-cycle in C2, we find this allows for a supersymmetric M5-brane probe which is related to the M2-brane probe which describes the BPS spectra of the corresponding N = 2 worldvolume gauge theory. For the case of M5-branes wrapping ...
متن کاملLiouville and Toda Solitons in M - theory
We study the general form of the equations for isotropic single-scalar, multi-scalar and dyonic p-branes in superstring theory and M-theory, and show that they can be cast into the form of Liouville, Toda (or Toda-like) equations. The general solutions describe non-extremal isotropic p-branes, reducing to the previously-known extremal solutions in limiting cases. In the non-extremal case, the d...
متن کاملModular Bootstrap for Boundary N = 2 Liouville Theory
We study the boundary N = 2 Liouville theory based on the “modular bootstrap” approach. As fundamental conformal blocks we introduce the “extended characters” that are defined as the proper sums over spectral flows of irreducible characters of the N = 2 superconformal algebra (SCA) and clarify their modular transformation properties in models with rational central charges. We then try to classi...
متن کاملExact Operator Solution of A2-Toda Field Theory
Quantum A2-Toda field theory in two dimensions is investigated based on the method of quantizing canonical free field. Toda exponential operators associated with the fundamental weights are constructed to the fourth order in the cosmological constant. This leads us to a conjecture for the exact operator solution. It is well-known that Toda field theories in two dimensions admit exact classical ...
