(7月21日）Spectral dimension and the essentially finite type condition for measures

报告人: Prof. Sze-Man Ngai (倪思敏，Georgia Southern Univeristy，湖南师范大学)题目：Spectral dimension and the essentially finite type condition for measures.摘要：The spectral dimension of the Laplacian defined by a measure has been shown to be closely related to heat kernel estimates, which under suitable conditions determine whether wave propagates with finite or infinite speed. We observe that...

（7月21日）On a recursive construction of Dirichlet form on the Sierpinski gasket

报告人: 邱华教授（南京大学）题目：On a recursive construction of Dirichlet form on the Sierpinski gasket.摘要：Let $/Gamma_n$ denote the $n$-th level Sierpinski graph of the Sierpinski gasket $K$. We consider, for any given conductance $(a_0, b_0, c_0)$ on $/Gamma_0$, the Dirchlet form ${/mathcal E}$ on $K$ obtained from a recursive construction of compatible sequence of conductances $(a_n, ...

(7月14日)大衍求一术和大衍总数术的算法意义与分析

报告题目：大衍求一术和大衍总数术的算法意义与分析}报告人：许光午(University of Wisconsin-Milwaukee， USA)摘要：计算模逆在公钥密码学中是最基本的运算之一。例如，在RSA中导出私钥和在DSA (ECDSA)　中生成签名都需要模逆。我们的主要目的是阐明秦九韶所记载的大衍求一术是计算模逆的最简洁直接的方法。我们将在讲座的第一部分对大衍求一术给予有特别之处的解释。在讲座的第二部分，我们进一步探讨秦九韶所记载和发展的大衍...
