Recently, Srivastava and Pintér 1 investigated several interesting properties and relationships involving the classical as well as the generalized (or higher-order) Bernoulli and Euler polynomials. ...They also showed (among other things) that the main relationship (proven earlier by Cheon 2) can easily be put in a much more general setting. The main object of the present sequel to these earlier works is to derive several general properties and relationships involving the Apostol-Bernoulli and Apostol-Euler polynomials. Some of these general results can indeed be suitably specialized in order to deduce the corresponding properties and relationships involving the (generalized) Bernoulli and (generalized) Euler polynomials. Other relationships associated with the Stirling numbers of the second kind are also considered.

A molecular model of the Pc(4457) and Pc(4440) LHCb states is proposed. The model relies on channels coupled by long-range pion-exchange dynamics with features that depend crucially on the novel ...addition of the Λc(2595)D¯ channel. A striking prediction of the model is the unusual combination of quantum numbers JP(4457)=1/2+ and JP(4440)=3/2−. Unlike in other models, a simultaneous description of both states is achieved without introducing additional short-range interactions. The model also gives a natural explanation for the relative widths of the states. We show that the usual molecular scenarios cannot explain the production rate of Pc states in Λb decays and that this can be resolved by including Λc(2595)D¯ and related channels. Experimental tests and other states are discussed in the conclusions.
Recently, the authors introduced some generalizations of the Apostol–Bernoulli polynomials and the Apostol–Euler polynomials (see Q.-M. Luo, H.M. Srivastava, J. Math. Anal. Appl. 308 (2005) 290–302 ...and Q.-M. Luo, Taiwanese J. Math. 10 (2006) 917–925). The main object of this paper is to investigate an analogous generalization of the Genocchi polynomials of higher order, that is, the so-called Apostol–Genocchi polynomials of higher order. For these generalized Apostol–Genocchi polynomials, we establish several elementary properties, provide some explicit relationships with the Apostol–Bernoulli polynomials and the Apostol–Euler polynomials, and derive various explicit series representations in terms of the Gaussian hypergeometric function and the Hurwitz (or generalized) zeta function. We also deduce their special cases and applications which are shown here to lead to the corresponding results for the Genocchi and Euler polynomials of higher order. By introducing an analogue of the Stirling numbers of the second kind, that is, the so-called λ-Stirling numbers of the second kind, we derive some basic properties and formulas and consider some interesting applications to the family of the Apostol type polynomials. Furthermore, we also correct an error in a previous paper Q.-M. Luo, H.M. Srivastava, Comput. Math. Appl. 51 (2006) 631–642 and pose two open problems on the subject of our investigation.
In previous works, we proved that under a certain assumption, the set of rational points over a number field on the Shimura curve of Γ 0 ( p ) -type consists of at most elliptic points for every ...sufficiently large prime number p. In this article, we relax the assumption of the previous result and prove the non-existence of elliptic points under a mild extra assumption.
The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control ...should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is whole number knowledge, then it should hinder fraction understanding. These predictions were tested in a racially and socioeconomically diverse sample of U.S. children (N = 765; 337 female) in Grades 3 (ages 8-9), 5 (ages 10-11), and 7 (ages 12-13) who completed a battery of computerized tests. The fraction comparison task included problems with both shared components (e.g., 3/5 > 2/5) and distinct components (e.g., 2/3 > 5/9), and problems that were congruent (e.g., 5/6 > 3/4) and incongruent (e.g., 3/4 > 5/7) with whole number knowledge. Inhibitory control predicted fraction comparison performance over and above working memory across component and congruency types. Whole number knowledge did not hinder performance and instead positively predicted performance for fractions with shared components. These results highlight a role for inhibitory control in rational number understanding and suggest that its contribution may be distinct from inhibiting whole number magnitude knowledge.
Public Significance Statement
Many students struggle to master fractions, potentially because of interference from their prior whole number knowledge. Consistent with this explanation, we found that students with better inhibitory control-the ability to resolve interference-had better fraction performance. However, the results did not suggest that whole number magnitude knowledge was the source of interference. These results highlight the role of inhibitory control in developing fraction understanding in elementary and middle school.
The main objective in this paper is first to establish new identities for the λ-Stirling type numbers of the second kind, the λ-array type polynomials, the Apostol–Bernoulli polynomials and the ...Apostol–Bernoulli numbers. We then construct a λ-delta operator and investigate various generating functions for the λ-Bell type numbers and for some new polynomials associated with the λ-array type polynomials. We also derive several other identities and relations for these polynomials and numbers.
