  • Cauchy Problem for Differential Operators with Double Characteristics
    Tatsuo Nishitani
    Combining geometrical and microlocal tools, this monograph gives detailed proofs of many well/ill-posed results related to the Cauchy problem for differential operators with non-effectively hyperbolic double characteristics. Previously scattered over numerous different publications, the results are presented from the viewpoint that the Hamilton map and the geometry of bicharacteri...

  • Hyperbolic Systems with Analytic Coefficients
    Tatsuo Nishitani
    This monograph focuses on the well-posedness of the Cauchy problem for linear hyperbolic systems with matrix coefficients. Mainly two questions are discussed:(A) Under which conditions on lower order terms is the Cauchy problem well posed?(B) When is the Cauchy problem well posed for any lower order term?For first order two by two systems with two independent variables with rea...

  • The Hyperbolic Cauchy Problem
    Kunihiko Kajitani / Tatsuo Nishitani
    The approach to the Cauchy problem taken here by the authors is based on theuse of Fourier integral operators with a complex-valued phase function, which is a time function chosen suitably according to the geometry of the multiple characteristics. The correctness of the Cauchy problem in the Gevrey classes for operators with hyperbolic principa...
