Academy of Mathematics and Systems Science, CAS Colloquia & Seminars： On the dimension of limit sets on the real projective plane via stationary measures
实射影平面 极限集 维数 平稳测度
2023/11/29
I will present a dimension jump result of limit sets on RP^2 for representations of surface groups in SL(3,R). For Anosov representations, we prove the equality between the Hausdorff dimension and the...

Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Some conjectures on real-rootedness
实根性 组合数学 大群多项式
2023/4/21
The real-rootedness has been drawing attention of many mathematicians to study them on a large group of polynomials in Combinatorics. This talk is concerned with some conjectures on the real-rootednes...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Twisted Real quasi-elliptic cohomology
扭曲 实拟椭圆 上同调
2023/4/13
Quasi-elliptic cohomology is closely related to Tate K-theory. It is constructed as an object both reflecting the geometric nature of elliptic curves and more practicable to study than most elliptic c...
How, and for what purpose, are cities and populations tracked, virtualized, and simulated by computational infrastructures in realtime? The semester's second Preston Thomas Memorial Symposium — "Real ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Real-time tool path planning using deep learning for subtractive manufacturing
深度学习 减材制造 实时刀具 路径规划
2023/4/25
Tool path planning is a crucial factor of computer-aided design and manufacturing (CAD/CAM). To generate suitable tool paths, the previous methods often transform the problem into local or global opti...
Cornell researchers have for the first time successfully imaged the entire depth of the lymph nodes in a living mouse using three-photon microscopy. The breakthrough technique’s micrometer clarity and...
Computers can learn to find solar flares in vast streams of images and help scientists issue timely space weather alerts, according to a new NSF-funded study. The research was published in the Journal...
An ancient desert covered in sand dunes as far as the eye could see, where dinosaurs and small mammals once roamed, may have been the real Jurassic Park. Today, the Navajo Sandstone, as it's called, i...
