Foreward Dear Friends, Welcome to the International Conference on Orthogonal Polynomials and q-series (May 10—12, 2015) at University of Central Florida, Orlando, Florida. This conference is dedicated to Professor Mourad Ismail on his 70th birthday. The main themes are two topics in which Mourad has made fundamental contributions. The organizing committee would like to extend sincere thanks for your coming to the conference held in sunny Orlando. Many of you came from different places far and near. Special welcome to the European, Middle Eastern and Chinese participants for making such a long journey to be with us and share this celebration and conference. We hope you will enjoy the stay and take advantage of being in the great Orlando area and to visit our world class attractions and some neighboring sites. Due to your presence and participation, we believe that the conference will be successful, and it will promote and enhance collaborations/interactions among scholars from different areas, both geographically and mathematically. Publication of the Proceeding of the Conference is planned. We thank Linda Perez-Rodriguez, Janice Burns and Doreen Goulding for their help. We would like to express our acknowledgement to the following organizations/units for their financial support: University of Central Florida King Saud University College of Science, UCF Department of Mathematics, UCF Our acknowledgement also goes to Elsevier Publisher and Pearson Higher Education.

I will describe a few of these. The second part of the talk will be completely different, no orthogonal polynomials or q-series, just a few inequalities involving polynomials and some consequences. George Andrews ([email protected]) { The Pennsylvania State University Bressoud's easy proof of the Rogers-Ramanujan identities and Bressoud polynomials Abstract: In 1974, a multiple series generalization of the Rogers-Ramanujan identities was proved. In 1983, David Bressoud published \An Easy Proof of the Rogers-Ramanujan identities." The main body of the paper provided exactly what was promised in the title. The paper concludes with a multiple series of generalization that has multiple suprises beneath the surface. We hope to illuminate some these surprises. Bruce Berndt ([email protected]) { University of Illinois at Urbana-Champaign Mathematical Connections Between Ramanujan and Hardy in Ramanujan's Earlier Notebooks and Lost Notebook Abstract: The joint work of Hardy and Ramanujan in their published papers continues to have a huge impact on contemporary research in number theory, combinatorics, and analysis. We do not discuss these contributions in this talk, but instead focus on the impact that each had on the other as evinced in several entries in the notebooks and lost notebook. The famous unsolved circle, divisor, and extended divisor problems, and the Riemann zeta function are featured. Most of this lecture is based on joint work with Atul Dixit, Sun Kim, Arindam Roy, and Alexandru Zaharescu. M. El Bachraoui ([email protected]) { UAE University On polynomiality of q-binomial coefficients Abstract: We provide a characterization of the polynomiality of the q-binomial coefficients and therefore also a characterization of congruence for the binomial coefficients. As an application we give a simple proof for a recent theorem by Guo and Krattenthaler. Yang Chen ([email protected]) { University of Macau, China Hankel determinants, singular perturbation, greater to lesser Painleve III Abstract: In this talk, I will discuss Hankel determinant generated by a Laguerre weight multiplied by exp(−t=x); t > 0, inducing an infinitely fast 0 at the origin. For finite n, the Hankel determinant, is expressed in terms a finite n Painleve III. Under double scaling where n ! 1 and t ! 0, such that s := 2nt is finite, the original PIII becomes a lesser PIII. The large s asymptotic expansion of the scaled, and in some sense, infinite determinant is obtained. This talk ends with a discussion of the constant term in the large s expansion.
