- Lectures

The moduli space M_g of genus g curves (or Riemann surfaces) is a central object of study in algebraic geometry. Its cohomology is important in many fields.

- Lectures

Coding is the last step in writing a program. The first step is deciding what we want to achieve and how. The best methods for working through subsequent steps consist in using simple mathematics…

- Lectures

We will give an accessible introduction to the Hasse-Weil conjecture for curves and related problems in the Langlands program. We will discuss some recent work with G. Boxer, F. Calegari and T.

- Lectures

Illusions have been a constant source of amusement but they are also a unique gateway into understanding the way we perceive the world and how the brain processes information. …

- Lectures

Suppose you wish to find a 2^n by 2^n matrix by asking this matrix question that it honestly answers. For example you can ask question "What is your (1,1) element?’"

- Lectures

Harmonic measure is the probability that a Brownian traveler starting from the center of the domain exists through a particular portion of the boundary.

- Lectures

How can we make it harder to misuse powerful AI systems, such as GPT-4, for propaganda, fraud, academic cheating, copyright violation, and so on?

- Lectures

...in this field, almost everything is already discovered, and all that remains is to fill a few unimportant holes." Philipp von Jolly in his recommendation to Max Planck not to go into physics.…

- Conferences & Workshops

- Lectures

I will discuss recent progress on counting the number of isomorphism classes of curves of a given genus over a finite field, with and without marked points, and applications to the cohomology of…

- Lectures

Doodling is a creative and fundamentally human activity, resulting in doodles with intricate and often hidden implicit structure.

- Lectures

The question of whether a smooth complex variety with a positive first Chern class, called a Fano variety, has a Kahler-Einstein metric has been a major topic…

Camera as Witness Stanford Arts presents the **REFLECTIONS**** **series celebrating** **the UN International Day of Women and…

- Lectures

In this lecture, we present a new method to solve the scattering problem defined by two planar, rectangular, semi-infinite open wave guides that meet along a common perpendicular line.

- Lectures

There are fascinating combinatorial problems arising from that study.
