+==== Spring 2021 ====
+** A Special Event: **
+Professor Ken Ono (University of Virginia), who is a Phi Beta Kappa Visiting Scholar this year, is  virtually visiting our department on  March 11-12. He will present three lectures via zoom,
+a Math Club Talk for undergraduate and graduate students with interest in mathematics,
+a Colloquium Talk for our faculty and graduate students,
+and a Public Lecture intended for a general audience.
+Details of these talk are given below.
+The talks are sponsored by our local Phi Beta Kappa Chapter.
+Many thanks to Professor Alex Feingold for organizing this.
+**Thursday March 11, 2:50-3:50pm, THIS IS THE MATH CLUB TALK [[https://binghamton.zoom.us/j/97188526236|Zoom Link]]**\\  //Speaker//: ** [[ https://uva.theopenscholar.com/ken-on | Ken Ono]] ** (University of Virginia) \\ //Topic//:
+What is the Riemann Hypothesis, and why does it matter? \\
+<WRAP box 90%>
+//Abstract//: The Riemann hypothesis provides insights into the distribution
+of prime numbers, stating that the nontrivial zeros of the Riemann zeta
+function have a “real part” of one-half. A proof of the hypothesis would
+be world news and fetch a $1 million Millennium Prize. In this lecture,
+Ken  Ono will discuss the mathematical meaning of the Riemann hypothesis
+and why it matters. Along the way, he will tell tales of mysteries about
+prime numbers and highlight new advances.

+//Topic//: Gauss’ Class Number Problem \\
+<WRAP box 90%>
+//Abstract//: In 1798 Gauss wrote Disquisitiones Arithmeticae, the first
+rigorous text in number theory. This book laid the groundwork for modern
+algebraic number theory and arithmetic geometry. Perhaps the most
+important contribution in the work is Gauss's theory of integral
+quadratic forms, which appears prominently in modern number theory (sums
+of squares, Galois theory, rational points on elliptic
+curves,L-functions, the Riemann Hypothesis, to name a few). Despite the
+plethora of modern developments in the field, Gauss’s first problem
+about quadratic forms has not been optimally resolved. Gauss's class
+number problem asks for the complete list of quadratic form
+discriminants with class number h. The difficulty is in effective
+computation, which arises from the fact that the Riemann Hypothesis
+remains open. To emphasize the subtlety of this problem, we note that
+the first case, where h=1, remained open until the 1970s. Its solution
+required deep work of Heegner and Stark, and the Fields medal theory of
+Baker on linear forms in logarithms. Unfortunately, these methods do not
+generalize to the cases where h>1. In the 1980s, Goldfeld, and Gross and
+Zagier famously obtained the first effective class number bounds by
+making use of deep results on the Birch and Swinnerton-Dyer Conjecture.
+This lecture will tell the story of Gauss’s class number problem, and
+will highlight new work by the speaker and Michael Griffin that offers
+new effective results by different (and also more elementary) means. \\

+Why does Ramanujan, “The Man Who Knew Infinity”, matter?
+\\ **Since this talk is open to the general public, we require registration in advance for this meeting:
+[[https://binghamton.zoom.us/meeting/register/tJMod-isrDooGN03CN34yKnEezYWNrdOrnnX|Use this link to preregister.]]
+After registering, you will receive a confirmation email containing information about joining the meeting.**

+//Abstract//: This lecture is about Srinivasa Ramanujan, “The Man Who Knew
+Infinity.” Ramanujan was a self-trained two-time college dropout who
+left behind 3 notebooks filled with equations that mathematicians are
+still trying to figure out today. He claimed that his ideas came to him
+as visions from an Indian goddess. This lecture gives many reasons why
+Ramanujan matters today. The answers extend far beyond his legacy in
+science and mathematics. The speaker was an Associate Producer of the
+film “The Man Who Knew Infinity” (starring Dev Patel and Jeremy Irons)
+about Ramanujan. He will share several clips from the film in the
+lecture, and will also tell stories about the production and promotion
+of the film.
