Invariant subspaces and conditional Lie-Backlund symmetries of inhomogeneous nonlinear difusion equations QU ChangZheng&JI LiNa Abstract The inhomogeneous nonlinear difusion equation is studied by invariant subspace and conditional LieBa¨cklund symmetry methods.It is shown that the equations admit a class of invariant subspaces governed by
