On the afternoon of May 19th, the Mathematics Master Lecture Series hosted by the School of Mathematical Sciences at Jiangsu University was held in the Third Lecture Hall of the Conference Center. The event featured a captivating presentation titled "L-functions and Arithmetic" delivered by renowned mathematician Professor Tian Ye, an Academician of the Chinese Academy of Sciences and researcher at the Academy of Mathematics and Systems Science. The lecture was chaired by Professor Tian Lixin, former Vice President of Jiangsu University.

Academician Tian Ye commenced his report by revisiting Fermat's classic problems, gradually unfolding the rich history of L-functions. He meticulously traced their evolution from conceptual beginnings to progressive development, highlighting how breakthroughs at each stage embodied the collective wisdom and dedication of generations of mathematicians. His insights illuminated the historical context, cutting-edge advancements, and profound connections between L-functions and arithmetic challenges for researchers.

Drawing upon his extensive research experience, Academician Tian adeptly demystified the intricate theory of L-functions in the study of congruent number problems. He transformed abstract concepts into accessible knowledge, offering the audience a vivid and profound understanding of both congruent number problems and the practical applications of L-functions. Attendees—faculty and students alike—became fully immersed, as if journeying through the historical currents of number theory development, witnessing the sparkling brilliance ignited by the collision of mathematical ideas.
