The annual International Diffiety School was founded in 1998. The School are designed to form a step-by-step introduction to the methods and ideology of Diffeotopy and Secondary Calculus, in particular, to a number of mathematical theories, such as the theory of infinite dimensional jet manifolds, contemporary differential geometry and topology, Lie groups and algebras, commutative and cohomological algebra.

The aim of the school is to introduce undergraduate and graduate students in Mathematics and Physics, as well as post-doctoral researchers and other mathematicians into a recently emerged area of mathematics and theoretical physics:

Secondary Calculus

Secondary calculus is the result of a natural evolution of the classical geometrical theory of partial differential equations (PDE) originated by Sophus Lie. In particular, it allows the construction of a general theory of PDE, in the same manner as algebraic geometry does with respect to algebraic equations. There are strong indications that secondary calculus may become a natural language for quantum field theory, just in the same way as standard calculus is for classical physics. From the mathematical point of view, secondary calculus is a complex mathematical construction putting into a natural interrelation many parts of modern mathematics such as commutative and homological algebra, algebraic and differential topology, differential geometry, etc. The strategic goal of the school is to involve interested participants into a series of large scale research programs the Diffiety Institute is launching.
