Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Vanishing of some algebraic cycles on powers of Shimura curves
志村曲线 幂 代数 循环消失
2023/4/27
For a smooth projective variety over a number field, the Beilinson—Bloch conjecture predicts that Chow groups of algebraic cycles modulo rational equivalence can be determined using cohomological data...
When a master chef develops a new cake recipe, she doesn’t try every conceivable combination of ingredients to see which one works best. The chef uses prior baking knowledge and basic principles to mo...
A new perspective on the powers of two descent for discrete logarithms in finite fields
foundations discrete logarithm problem
2018/7/9
A new proof is given for the correctness of the powers of two descent method for computing discrete logarithms. The result is slightly stronger than the original work, but more importantly we provide ...

New ultrathin semiconductor materials silicon secret powers Stanford engineers
2017/9/5
The next generation of feature-filled and energy-efficient electronics will require computer chips just a few atoms thick. For all its positive attributes, trusty silicon can’t take us to these ultrat...
A little fluorine turns an insulating ceramic known as white graphene into a wide-bandgap semiconductor with magnetic properties. Rice University scientists said that could make the unique material su...
Representing Quantum Superpositions:Powers,Potentia and Potential Effectuations
quantum superposition potentiality powers potentia
2016/6/12
In this paper we attempt to provide a physical representation of quantum superpositions. For this purpose we discuss the constraints of the quantum formalism to the notion of possibility and the neces...
REVIEW OF Getting Causes from Powers,by Stephen Mumford and Rani Lill Anjum
Causation powers dispositions simultaneous causation vectors
2016/5/30
In this book, Mumford and Anjum advance a theory of causation based on a metaphysics of powers. The book is for the most part lucidly written, and contains some interesting contributions: in particula...
