N2 - We introduce a generalization of Ar-type Toda theory based on a non-Abelian group G, which we call the (Ar, G)-Toda theory, and its affine extensions in terms of gauged Wess-Zumino-Witten actions with deformation terms. In particular, the affine (A1, 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 (A1, 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.
