A Diagonal on the Associahedra
نویسنده
چکیده
Let C∗ (K) denote the cellular chains on the Stasheff associahedra. We construct an explicit combinatorial diagonal ∆ : C∗(K) → C∗(K)⊗C∗(K); consequently, we obtain an explicit diagonal on the A∞-operad. We apply the diagonal ∆ to define the tensor product of A∞-(co)algebras in maximal generality.

An associahedral set is a combinatorial object generated by Stasheff associahedra {Kn} and equipped with appropriate face and degeneracy operators. Associahedral sets are similar in many ways to simplicial or cubical sets. In this paper we give a formal definition of an associahedral set, discuss some naturally occurring examples and construct an explicit geometric diagonal ∆ : C∗(Kn) −→ C∗(Kn)...
متن کاملGraph Properties of Graph Associahedra
A graph associahedron is a simple polytope whose face lattice encodes the nested structure of the connected subgraphs of a given graph. In this paper, we study certain graph properties of the 1-skeleta of graph associahedra, such as their diameter and their Hamiltonicity. Our results extend known results for the classical associahedra (path associahedra) and permutahedra (complete graph associa...
متن کاملQuantitative Non-diagonal Regulator Design for Uncertain Multivariable System with Hard Time-domain Constraints
In this paper a non-diagonal regulator, based on the QFT method, is synthesized for an uncertain MIMO plant whose output and control signals are subjected to hard time-domain constraints. This procedure includes the design of a non-diagonal pre-controller based on a new simple approach, followed by the sequential design of a diagonal QFT controller. We present a new formulation for the latter s...
متن کاملBlock Diagonal Majorization on $C_{0}$
Let $mathbf{c}_0$ be the real vector space of all real sequences which converge to zero. For every $x,yin mathbf{c}_0$, it is said that $y$ is block diagonal majorized by $x$ (written $yprec_b x$) if there exists a block diagonal row stochastic matrix $R$ such that $y=Rx$. In this paper we find the possible structure of linear functions $T:mathbf{c}_0rightarrow mathbf{c}_0$ preserving $prec_b$.
متن کاملVisibility Graphs and Deformations of Associahedra
The associahedron is a convex polytope whose face poset is based on nonintersecting diagonals of a convex polygon. In this paper, given an arbitrary simple polygon P , we construct a polytopal complex analogous to the associahedron based on convex diagonalizations of P . We describe topological properties of this complex and provide realizations based on secondary polytopes. Moreover, using the...
