A Legendre Polynomial Integral [PDF]

open access: yesMathematics of Computation, 1979
Let { P n ( x ) } \{ {P_n}(x)\} be the usual Legendre polynomials. The following integral is apparently new. \[ ∫ 0 1 P n ( 2 x

Integrability for Nonlinear Time-Delay Systems [PDF]

open access: yes, 2016
In this note, the notion of integrability is defined for 1-forms defined in the time-delay context. While in the delay-free case, a set of 1-forms defines a vector space, it is shown that 1-forms computed for time-delay systems have to be viewed as ...

Absorption of closed strings by giant gravitons

open access: yesJournal of High Energy Physics, 2019
A new approach to the computation of correlation functions involving two determinant operators as well as one non-protected single trace operator has recently been developed by Jiang, Komatsu and Vescovi.

Computing necessary integrability conditions for planar parametrized homogeneous potentials [PDF]

open access: yes, 2014
Let $V\in\mathbb{Q}(i)(\a_1,\dots,\a_n)(\q_1,\q_2)$ be a rationally parametrized planar homogeneous potential of homogeneity degree $k\neq -2, 0, 2$. We design an algorithm that computes polynomial \emph{necessary} conditions on the parameters $(\a_1 ...

Global attractors for a class of semilinear degenerate parabolic equations

open access: yesOpen Mathematics, 2021
In this paper, we consider the long-time behavior for a class of semi-linear degenerate parabolic equations with the nonlinearity ff satisfying the polynomial growth of arbitrary p−1p-1 order.

Perturbative analysis of the colored Alexander polynomial and KP soliton τ-functions

open access: yesNuclear Physics B, 2021
In this paper we study the group theoretic structures of colored HOMFLY polynomials in a specific limit. The group structures arise in the perturbative expansion of SU(N) Chern-Simons Wilson loops, while the limit is N→0.

Inversion Integrals Involving Jacobi's Polynomials [PDF]

open access: yesProceedings of the American Mathematical Society, 1964
These standardizations for 13= 1/2 reduce to the standardized Gegenbauer polynomials used by Buschman when k is an even integer in [2]. Thus the results of [2] are particular cases of those given here when k is an even integer. A generalization, for the case when k is an odd integer in the standardizations used by Buschman, appears to be impossible ...

Integral Formulae of Bernoulli Polynomials [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2012
Recently, some interesting and new identities are introduced in (Hwang et al., Communicated). From these identities, we derive some new and interesting integral formulae for the Bernoulli polynomials.
