题目：算子函数演算的 Weyl 定理及其稳定性

摘要：有界线性算子的Weyl 定理对于算子谱理论的研究有着重要意义。在本报告中, 我们分别研究了Hilbert 空间上的有界线性算子\ $T$ 及其正整数次幂$T^n$的 Weyl 定理的稳定性, 并且探索了两者之间的关系。

题目：The Equivariant Higher Index Map for Proper  -space and Coarse Embedding

摘要：Let be a discrete metric space with bounded geometry, a countable discrete group. Assume that acts on  properly and isometrically, in this case we call  a -space. There is an equivariant higher index map Where is the  -equivariant -homology group of the Rips complex ,is the  -theory group of the equivariant Roe algebra  for the  -space .The isomorphism or the injectivity of this map has many applications in geometry and topology.If   and   can be coarsely embedded into a Hilbert space respectively, then the equivariant higher index map above is injective. This is a joint work with Xianjin Wang and Guoliang Yu.

题目: Bases, frames, and operator-valued measures on Banach and operator spaces

摘要: We introduce the concept of (Schauder) frames for Banach and operator spaces, give the concrete example for reduced free group C*-algebra, and show the connection with the (completely) bounded approximation property and complemented embedding, and give the duality theorems for frames and associated basis in reflexive Banach spaces. A general dilation theory of operator-valued measures and frames for Banach spaces is motivated by the observation that there is a connection between the analysis of dual pairs of frames (both the discrete and the continuous theory) and the dilation theory of operator-valued measures on Banach spaces. As a continuation of our recent work, we show that every operator-valued measure with bounded p-variation can be dilated to a projection-valued measure preserving the same variation property on a dilation Banach space.

题目:  Transition probability preserving maps in semifinite factors

摘要：In this talk, I will state the brief history about the Wigner's theorem, which is one of the cornerstones of the mathematical formulation of quantum mechanics, asserts that every symmetry of quantum system is unitary or anti-unitary. I will provide a new approach to describe the general form of the transition probability preserving (not necessarily bijective) maps between Grassmann spaces in semifinite factors.

题目：On singular characteristic in cryptanalysis

摘要：Many lightweight block ciphers employ a very simple key schedule in which the round keys only differ by addition of a round specific constant. In this paper, we investigate how differential cryptanalysis is affected with these ciphers. By taking PRINCE, Midori and AES as examples, we show some theoretical ``good" different characteristics with high probabilities are impossible due to the values of round constants. We call this kind of differential path the singular differential characteristic. We reveal the precise mathematical properties which are behind this phenomenon.  Moreover, our method can be applied to check the validity of differential characteristics of the other block ciphers with simple key schedules. To be positive, we also give some valid 3-round distinguishers and 4-round distinguishers for the PRINCE block cipher, by using Mixed Integer Linear Programming(MILP) and taking account of round constants into consideration.
