Boris Kruglikov "Applications of commutative algebra to PDEs -II".

This time I will discuss resolutions and syzygies of differential ideals. Definition and properties of differential Groebner basis will be given, which apply to compatibility conditions of systems of differential equations. We will compare these results to the compatibility via brackets criterea, discussed on the seminar earlier.
