The Principal Investigator proposes to use techniques from analysis, in particular from the study of heat and wave kernels and distribution theory, to study zeta functions of number theory. In the field of regular graphs, both finite and infinite, the project will systematically develop a heat kernel approach to number theory on graphs, including the Ihara zeta function. In previous work, the PI has developed a succinct relation between Fourier coefficients of weight zero Maass forms and weight two holomorphic forms, both associated to any finite volume hyperbolic Riemann surface. The proposal involves a continuation of this work, striving toward bounds of the Fourier coefficients.Both the heat kernel and the wave kernel are mathematical objects which admit interpretations from many mathematical fields. The heat kernel, in particular, can be viewed as a solution of a partial differential equation, as a one-parameter family of positive integrable functions, and as a function associated to probability theory and random walks. As a result, the heat kernel provides a means by which one can employ ideas and results from one mathematical discipline in order to approach problems in another field. The PI plans to continue this approach to study problems in number theory, analysis, and graph theory. In addition to research interests, the PI has undertaken a number of educational endeavors striving to enhance opportunities for students. As a faculty member at The City College of New York, the PI has developed courses in statistics and in financial mathematics for the Mathematics Department, and he works closely with the School of Education in their course offerings in teacher training programs. In October 2010, the PI, together with J. Kramer, taught a graduate level course at the University of Sarajevo. The proposed research includes a component of effort by the PI to enhance and further develop these teaching aspects of his mathematical interests.

首席研究员建议使用分析技术，特别是热和波核以及分布理论的研究技术，来研究数论的 zeta 函数。 在有限和无限正则图领域，该项目将系统地开发图数论的热核方法，包括 Ihara zeta 函数。 在之前的工作中，PI 开发了权重为零的 Maass 形式和权重两个全纯形式的傅里叶系数之间的简洁关系，两者都与任何有限体积双曲黎曼曲面相关。 该提案涉及这项工作的延续，努力达到傅里叶系数的界限。热核和波核都是数学对象，可以从许多数学领域进行解释。 特别是，热核可以被视为偏微分方程的解、正可积函数的单参数族以及与概率论和随机游走相关的函数。 因此，热内核提供了一种方法，人们可以通过该方法利用一个数学学科的思想和结果来解决另一个领域的问题。 PI 计划继续采用这种方法来研究数论、分析和图论中的问题。 除了研究兴趣之外，PI 还开展了许多教育工作，努力增加学生的机会。 作为纽约城市学院的教员，PI 为数学系开发了统计学和金融数学课程，并与教育学院在教师培训项目的课程设置中密切合作。 2010 年 10 月，PI 与 J. Kramer 一起在萨拉热窝大学教授研究生课程。 拟议的研究包括 PI 为增强和进一步发展其数学兴趣的这些教学方面所做的努力。
