Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Hard Lefschetz properties, complete intersections and numerical dimensions
莱夫谢茨数 性质 完整交集 数值尺寸
2023/4/19
In this talk, we discuss the positivity of complete intersections of nef classes, including sufficient and necessary characterizations of the hard Lefschetz property on a compact complex torus and the...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Large deviations principle for weighted means of a recursive numerical method for ergodic SDEs
遍历 SDE递归 数值方法 加权均值 大偏差原理
2023/4/24
For ergodic SDEs, their ergodic limits are usually approximated by the suitable means of numerical methods. To reveal the numerical asymptotic behavior, we study the large deviations principle (LDP) f...

Efficient numerical stability analysis detonation waves in ZND
2010/11/9
As described in the classic works of Lee--Stewart and Short--Stewart, the numerical evaluation of linear stability of planar detonation waves is a computationally intensive problem of considerable int...
Numerical Chaos in a Fractional Order Logistic Map
Numerical Chaos Fractional Order Logistic Map
2010/11/17
In this paper we investigate a fractional order logistic map and its discrete time dynamics. We show some basic properties of the fractional logistic map and numerically study its period-doubling rout...
We develop an intersection theory for a singular hemitian line bundle with positive curvature current on a smooth projective variety and irreducible curves on the variety. And we prove the existence ...
