We consider a diffusion (t)t0 with some T -periodic time dependent input term contained in the drift: under an unknown parameter # 2 , some discontinuity – an additional periodic signal – occurs at...

For a certain class of one-dimensional diffusions X(t); we
study the distribution of maxt2[0;T ] X(t) and the distribution of the first instant
at whichX(t) attains the maximum by reducingX(t) to Br...
