In this paper,we investigate some properties of q-Bernoulli polynomials arising from q-umbral calculus.We find a formula for expressing any polynomial as a linear combination of q-Bernoulli polynomials with explicit c... In this paper,we investigate some properties of q-Bernoulli polynomials arising from q-umbral calculus.We find a formula for expressing any polynomial as a linear combination of q-Bernoulli polynomials with explicit coefficients.Also,we establish some connections between q-Bernoulli polynomials and higher-order q-Bernoulli polynomials. 展开更多

In this note, we prove a formula which expresses the constant term of the spherical Eisenstein series on a quasi-split unitary group as a linear combination of spherical Eisenstein series on smaller unitary groups.

Asymptotic expansion of two Sheffer polynomials, namely, Charlier and Laguerre, was obtained by L,C, Hsu6]using a combinatorial method, In this paper, L,C, Hsu's method in [6]has been put into a formal theorem that the author successfully applied to four other Sheffer polynomials: Poisson-Charlier, weighted Touchard, Toscano, and Angelescu polynomials, Within sonic specified domains remainder estimates have been obtained, Moreover, sonic spplicability and llimitation have been mentioned, 展开更多
