Title: Algebras from oriented triangulated manifolds
By extracting the idea and techniques of classical cluster algebras, we construct a class of algebras from closed oriented triangulated even-dimensional manifolds by performing middle-dimensional （bistellar） moves. This class of algebras exhibit the algebraic behaviour of middle-dimensional （bistellar） moves, so the construction of this class of algebras has a quite difference from one of a classical cluster algebra. Moreover, we will use the algebras to construct PL invariants for PL manifolds. This is joint work with Alastair Darby and Fang Li.
