## Abstract

We introduce a generalization of A_{r}-type Toda theory based on a non-Abelian group G, which we call the (A_{r}, G)-Toda theory, and its affine extensions in terms of gauged Wess-Zumino-Witten actions with deformation terms. In particular, the affine (A_{1}, SU(2))-Toda theory describes the integrable deformation of the minimal conformal theory for the critical Ising model by the operator Φ_{(2,1)}. We derive infinite conserved charges and soliton solutions from the Lax pair of the affine (A_{1}, SU(2))-Toda theory. Another type of integrable deformation which accounts for the Φ_{(3,1)}-deformation of the minimal model is also found in the gauged Wess-Zumino-Witten context and its infinite conserved charges are given.
