The resolution of stochastic differential equations put a very complex problem. For this raison, we have presented a deep study (Continuous Generalized Auto Regressive Conditioned Heteroscedastic) (COGARCH), largely applied ...

The aim or goal of this work is to study some problems of nonlinear time series. The particular class of models nonlinear that was extensity discussed in the literature is he class of periodic bilinear models. The sufficient ...

This work is devoted to non-parametric test studies of population comparison based on complete, right censored data or categorically bouble censored ones. Illustration examples of studied methodes complete theoritical ...

In this work we studied the nonlocal spectral problem of second order following : First we are interested in studying the regularity and almost regularity of boundary conditions, and we determined in the case q (x) ...
