Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Characterizations of Separably Differentially Closed Fields
可分 微分闭域 微分场
2023/11/7
In this talk, we define a new class of differential fields called separably differentially closed fields and show their several characterizations by comparing them with differentially closed fields of...
Characterizations of the differential uniformity of vectorial functions by the Walsh transform
secret-key cryptography known APN functions
2017/6/6
For every positive integers nn, mm and every even positive integer δδ, we derive inequalities satisfied by the Walsh transforms of all vectorial (n,m)(n,m)-functions and prove that the case of equalit...

Characterizations of Shell and Mantle Edge Pigmentation of a Pacific Oyster, Crassostrea gigas, in Korean Peninsula
Pacific Oyster Shell Color Mantle Edge Heritability
2016/5/12
The objectives of this study were to investigate color patterns of shell and mantle edge pigmentation of a Pacific oyster, C. gigas, and to estimate variance components of the two colors. A sample of ...
Backstepping controller synthesis and characterizations of incremental stability
Backstepping controller synthesis characterizations of incremental stability Optimization and Control
2012/7/9
Incremental stability is a property of dynamical and control systems, requiring the uniform asymptotic stability of every trajectory, rather than that of an equilibrium point or a particular time-vary...
