%0 Journal Article %T Bernoulli-Taylor formula in the case of Q-umbral Calculus %A Ewa Krot-Sieniawska %J Mathematics %D 2007 %I arXiv %X In this note we derive the Q-difference Bernoulli-Taylor formula with the rest term of the Cauchy form by the Viskov's method. This is an extension of technique by the use of Q-extented Kwasniewski's *-product . The main theorems of Q-umbral calculus were given by G. Markowsky in 1968 and extented by A.K.Kwasniewski. %U http://arxiv.org/abs/0710.5806v1
