Abstract

Let Λ be a tubular algebra over an arbitrary base field. We study the Grothendieck group K0(Λ), endowed with the Euler form, and its automorphism group Aut(K0(Λ)) on a purely K-theoretical level as in [7]. Our results serve as tools for classifying the separating tubular families of tubular algebras as in the example [5] and for determining the automorphism group Aut(DbΛ) of the derived category of Λ.
