• symmetry algebra
• high-dimensional model
• invariant equation

Using every realization of the Virasoro-type symmetry algebra [sigma (f(1)), sigma (f(2))] = sigma((f) over dot(1)f(2) - (f) over dot(2)f(1)), we can obtain various high-dimensional integrable models under the meaning that they possess infinitely many symmetries. By means of a concrete realization, many (3 I)-dimensional equations which possess Kac-Moody-Virasoro-type infinite dimensional symmetry algebras are obtained.
