We investigate the coradical filtration of pointed coalgebras. First, we generalize a theorem of Taft and Wilson using techniques developed by Radford. We then look at the coradical filtration of duals of inseparable field extensions L \* upon extension of the base field K, where K βŠ† L is a field ex

In this paper we show that there is a close connection between the coradical filtration of a pointed coalgebra and the Hochschild cohomology of that coalgebra with coefficients in some one-dimensional bicomodules. As an application, for a given prime number p and an algebraically closed field k of c
