XII Winter Diffiety School
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, called "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.
