Symmetries of a flat cosymbol algebra of the differential operators
V. S. Kalnitsky St. Petersburg State University, St. Petersburg, Russia
Abstract:
In this paper the structure theorem is proved for graded symmetries of a flat cosymbol algebra. This theorem together with Equivariant Polynomials Lemma gives an upper bound on the grade dimensions of the Lie algebra of
symmetries.
Key words and phrases:
cosymbols of differential operators, pulverisation, symmetries of polynomial fields.
