“…For m 1 = m 2 = · · · = m n = 1, the above result was already known to Mongelli [12]. For m 1 = m 2 = · · · = m n = 1, the above result was already known to Mongelli [12].…”

“…where exc A (w) is the number of excedances of w at coordinates of zero color and csum(w) is the sum of the colors of all coordinates of w; more explanation appears in Section 2. The flag excedance statistic was introduced (although not with this name) by Bagno and Garber [5] and was further studied in [17] and, in the special case r = 2, in [16,21]. We will denote by D r n the set of derangements (elements without fixed points of zero color) in Z r ≀ S n .…”

“…Bagno and Garber [2] introduced a definition of excedance on the set of signed permutations, called colored excedance, exc Clr(σ) := 2exc A (σ) + neg(σ). Mongelli [27] defined the generating function of the colored descent statistic on B n by P n (B, q) = σ∈Bn q exc Clr (σ) and proved P n (B, q) = (1 + q) n P n (A, q). (3.6) Let D n (B) denote the set of all derangements on B n and d n (B, q) be the generating function of the colored excedances on the set D n (B), that is…”
