Avoiding Maximal Parabolic
Let [p] = {1, . . . , p} denote a totally ordered alphabet on p letters, and let α = (α1, . . . , αm) ∈ [p1] , β = (β1, . . . , βm) ∈ [p2] . We say that α is order-isomorphic to β if for all 1 6 i < j 6 m one has αi < αj if and only if βi < βj . For two permutations π ∈ Sn and τ ∈ Sk, an occurrence of τ in π is a subsequence 1 6 i1 < i2 < · · · < ik 6 n such that (πi1 , . . . , πik) is order-is...
متن کاملKazhdan-lusztig and R-polynomials, Young’s Lattice, and Dyck Partitions
We give explicit combinatorial product formulas for the maximal parabolic Kazhdan-Lusztig and R-polynomials of the symmetric group. These formulas imply that these polynomials are combinatorial invariants, and that the KazhdanLusztig ones are nonnegative. The combinatorial formulas are most naturally stated in terms of Young’s lattice, and the one for the Kazhdan-Lusztig polynomials depends on ...
متن کاملAvoiding maximal parabolic subgroups of Sk
Let [p] = {1, . . . , p} denote a totally ordered alphabet on p letters, and let α = (α1, . . . ,αm) ∈ [p1], β = (β1, . . . ,βm) ∈ [p2]. We say that α is order-isomorphic to β if for all 1≤ i< j ≤ m one has αi < α j if and only if βi < β j. For two permutations π ∈ Sn and τ ∈ Sk, an occurrence of τ in π is a subsequence 1 ≤ i1 < i2 < .. . < ik ≤ n such that (πi1 , . . . ,πik ) is order-isomorph...
متن کاملOn maximal parabolic regularity for non-autonomous parabolic operators
We consider linear inhomogeneous non-autonomous parabolic problems associated to sesquilinear forms, with discontinuous dependence of time. We show that for these problems, the property of maximal parabolic regularity can be extrapolated to time integrability exponents r 6= 2. This allows us to prove maximal parabolic L r-regularity for discontinuous non-autonomous second-order divergence form ...
متن کاملMaximal and Linearly Inextensible Polynomials
Let S(n, 0) be the set of monic complex polynomials of degree n ≥ 2 having all their zeros in the closed unit disk and vanishing at 0. For p ∈ S(n, 0) denote by |p|0 the distance from the origin to the zero set of p. We determine all 0-maximal polynomials of degree n, that is, all polynomials p ∈ S(n, 0) such that |p|0 ≥ |q|0 for any q ∈ S(n, 0). Using a second order variational method we then ...
