Tomer Schlank "Prismatic cohomology" (after Bhatt and Scholze) Abstract: We shall discuss (Weil) cohomology theories for algebraic varieties. When working with schemes over p-complete rings and taking cohomologies with p-complete coefficients one gets a plurality of such cohomology theories (e'tale, De-Rahm, Crystalline, etc.. ). The comparison between these different cohomology theories is a subtle subject known as "p-adic hodge theory" .

Elon Lindenstrauss "Arithmetic applications of diagonal flows" I will give an introduction to the dynamics of higher rank diagonal flows on homogeneous spaces, including both the rigidity theorems of such flows and their applications to orbits of arithmetic interest, in particular CM points and integer points on spheres. I hope to cover parts of the following papers: Einsiedler, Manfred ; Lindenstrauss, Elon ; Michel, Philippe ; Venkatesh, Akshay . The distribution of closed geodesics on the modular surface, and Duke's theorem. Enseign. Math. (2) 58 (2012), no. 3-4, 249--313.

Tentative syllabus 1. Mathematical models of classical and quantum mechanics. 2. Correspondence principle and quantization. 3. Classical and quantum computation: gates, circuits, algorithms (Shor, Grover). Solovay-Kitaev. Some ideas of cryptography 4. Quantum noise and measurement, and rigidity of the Poisson bracket. 5. Noisy classical and quantum computing and error correction, threshold theorem- quantum fault tolerance (small noise is good for quantum computation). Kitaev's surface code. 6. Quantum speed limit/time-energy uncertainty vs symplectic displacement energy.
