A q-analogue of a formula of Hernandez obtained by inverting a result of Dilcher
We prove a q-analogue of the formula by inverting a formula due to Dilcher. 1 The identities Hernandez in [6] proved the following identity:
متن کاملJumping Numbers of Hyperplane Arrangements
M. Saito [S] proved that the jumping numbers of a hyperplane arrangement depend only on the combinatorics of the arrangement. However, a formula in terms of the combinatorial data was still missing. In this note, we give a formula and a different proof of the fact that the jumping numbers of a hyperplane arrangement depend only on the combinatorics. We also give a combinatorial formula for part...
متن کاملOn Combinatorics of Quiver Component Formulas
Buch and Fulton [7] conjectured the nonnegativity of the quiver coefficients appearing in their formula for a quiver variety. Knutson, Miller and Shimozono [21] proved this conjecture as an immediate consequence of their “component formula”. We present an alternative proof of the component formula by substituting combinatorics for Gröbner degeneration [21, 20]. We relate the component formula t...
متن کاملNoncrossing partitions with fixed points
The noncrossing partitions with each of their blocks containing a given element are introduced and studied. The enumeration of these partitions is described through a polynomial of several variables which is proved to satisfy a recursive formula. It is shown that each variable increased by one is a factor of this polynomial.
متن کاملConstructive lower bounds for Ramsey numbers from linear graphs
Giraud (1968) demonstrated a process for constructing cyclic Ramsey graph colourings, starting from a known cyclic ‘prototype’ colouring, adding edges of a single new colour, and producing a larger cyclic pattern. This paper describes an extension of that construction which allows any number of new colours to be introduced simultaneously, by using two multicolour prototypes, each of which is a ...
