From Wikipedia, the free encyclopedia

In mathematics a diffiety, is a geometrical object introduced by Vinogradov (1984) playing the same role in the modern theory of partial differential equations as algebraic varieties play for algebraic equations.

Another way of generalizing ideas from algebraic geometry is differential algebraic geometry.
