Area of Science:

  • Mathematics
  • Partial Differential Equations

Background:

  • Darboux problems are a class of initial-boundary value problems for partial differential equations.
  • Polyvibrating equations are a generalization of wave equations, involving higher-order derivatives.
  • Analytic data refers to initial or boundary conditions specified by analytic functions.

Purpose of the Study:

  • To investigate and solve a specific type of Darboux problem for polyvibrating equations.
  • To apply and extend the F-function approach to a multi-variable context.

Main Methods:

  • Utilizing the F-function approach developed by C. Truesdell.
  • Extending the F-equations to accommodate functions of several variables.

Main Results:
