On regular irreducible components of module varieties over string   algebras
  We determine the regular irreducible components of the variety mod(A,d), where A=kQ/I is a string algebra and I is generated by a set of paths of length two. Our case is among the first examples of descriptions of irreducible components, aside from hereditary, tubular and Gelfand-Ponomarev algebras.
