Theory of normal forms of linear second order mixed type PDEs on the plane A. A. Davydovab a Vladimir State University b Lomonosov Moscow State University |

Abstract: This theory originates from the known treatise by F.Tricomi (1923), in which normal form for such an equation was proposed near a typical point of type change line, at which the characteristic direction is not tangent to the line. The correct proof for this form was given a decade later by M.Cibrario. Language: English |
