Abstract : By means of convenient regularization for an ill posed Cauchy problem, we define an associated generalized problem and discuss the conditions for the solvability of it. To illustrate this, starting from the semilinear unidirectional wave equation with data given on a characteristic curve, we show existence and uniqueness of the solution
Keywords : characteristic problems distributions nonlinear generalized functions nonlinear problems regularisation of problems regularization of data transport equation
