Geometric Transition for a Class of Hyperbolic Operators with Double Characteristics
Geometric Transition for a Class of Hyperbolic Operators with Double Characteristics
The Cauchy problem in the C ∞ category for hyperbolic operators with double characteristics has been studied by many authors under different geometrical perspectives. These results (see e.g. [11], [1] and the references therein) put in evidence the role of both the lower order terms and the symplectic geometry associated …
