Báo cáo toán học: "A uniform approach to complexes arising from forests" pps

... this paper we present a unifying approach to study the homotopy type of several complexes arising from forests. We show that this method applies uniformly to many complexes that have been extensively ... the concepts introduced in Section 3 to study simplicial complexes associated to forests. We shall see that all these complexes are grapes and are homotopic to wedges...

The applications of our method to other cases like ... + 1 x n . This completes the proof. Now we are ready to prove Theorem 1.2. Without loss of generality, we may assume r = 1 and s = 2 in Theorem 1.2. A new approach to Theorem 1.2....

From (7) it is not difficult to derive also a nonasymptotic expression for E LA n (µ): E LA n (µ) = n Osc ... of a uniform random permutation τ ∈ [n]. Classical probabilistic arguments are used to rederive the asymptotic mean, variance and limiting law of LA n (τ ). Our methodology is robust enoug...
