Let $ N $ be a nonassociative finite-dimensional simple Novikovalgebra over an algebraically closed field $ F $ of characteristic $ p>0 $ . Thenthe right multiplication algebra $ R $ is a differential simple algebrawith respect to some derivation $ d $ . The algebra $ N $ is isomorphicto a Novikov algebra $ (R,d,R_{x}) $ for some operator of right multiplication by $ x $ and multiplicationis given by $ u\circ w=ud(w)+R_{x}uw $ .Moreover, the algebra $ R $ is a truncated polynomial algebra.
