The present paper deals with the study of explosion and growth order of solutions of a general class of Ito-type stochastic integrodifferential equations which contain as a special case the study of Ito type stochastic differential equations. Sufficient conditions for infinite explosion time and asymptotic behavior of solutions are investigated.
In this note, a ‘definition’ of the useful but notorious Feynman measure corresponding to bilinear Lagrangeans with ‘singular’ coefficients is given through functional derivative equations. Especially, the procedures of renormalization and gauge fixing are clarified at the equation level.
