Relative Auslander Bijection in Extriangulated Categories
《Acta Mathematica Sinica,English Series》2025年第3期985-1014,共30页Tiwei Zhao 
Supported by NSFC(Grant No.11901341);Shandong Provincial Natural Science Foundation(Grant No.ZR2021QA001);Youth Innovation Team of Universities of Shandong Province(Grant No.2022KJ314)。
Extriangulated categories were introduced by Nakaoka and Palu, which unify exact categories and extension-closed subcategories of triangulated categories. In this paper, we develop the relative homology aspect of Ausl...

Research on enumeration problem of pattern-avoiding permutations
《Frontiers of Mathematics in China》2024年第4期191-213,共23页Tongyuan ZHAO Xiaoqing LI Feng ZHAO 
The problem of relevant enumeration with pattern-avoiding permutations is a significant topic in enumerative combinatorics and has wide applications in physics,chemistry,and computer science.This paper summarizes the ...

Practical construction of globally injective parameterizations with positional constraints
《Computational Visual Media》2023年第2期265-277,共13页Qi Wang Wen-Xiang Zhang Yuan-Yuan Cheng Ligang Liu Xiao-Ming Fu 
supported by the National Natural Science Foundation of China(61802359,62025207);USTC Research Funds of the Double First-Class Initiative(YD0010002003).
We propose a novel method to compute globally injective parameterizations with arbitrary positional constraints on disk topology meshes.Central to this method is the use of a scaffold mesh that reduces the globally in...

The authors would like to thank Dong Yang and Yuefei Zheng for their helpful discussion. This work was partially supported by the National Natural Science Foundation of China （Grant No. 11571164） and a Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions.
Motivated by T-tilting theory developed by T. Adachi, O. Iyama, I. Reiten, for a finite-dimensional algebra A with action by a finite group G, we introduce the notion of G-stable support τ-tilting modules. Then we es...

An Operator on Ascent Sequences
《Wuhan University Journal of Natural Sciences》2014年第4期289-294,共6页YING Changtian YU Jiong 
Supported by the National Natural Science Foundation of China(61262088,61063042);the Natural Science Foundation Project of Xinjiang Uygur Autonomous Region(2011211A011)
We solve two problems about ascent sequences： how to get the ascent sequence of the reflection of A with respect to its antidiagonal for a matrix A ∈ Intn and its ascent sequences, and how to determine the ascent se...

On Classification of k-Dimension Paths in n-Cube
《Applied Mathematics》2014年第4期723-727,共5页G. G. Ryabov V. A. Serov 
The shortest k-dimension paths (k-paths) between vertices of n-cube are considered on the basis a bijective mapping of k-faces into words over a finite alphabet. The presentation of such paths is proposed as (n - k +...

Let S be a locally inverse semigroup with an inverse transversal S°.In this paper,we construct an amenable partial order on S by an R-cone.Conversely,every amenable partial order on S can be constructed in this way.W...

Adjacency Preserving Bijection Maps of Hermitian Matrices over any Division Ring with an Involution被引量：6
《Acta Mathematica Sinica,English Series》2007年第1期95-102,共8页Li Ping HUANG 
the National Natural Science Foundation of China Grant,#10271021
Let D be any division ring with an involution,Hn （D） be the space of all n × n hermitian matrices over D. Two hermitian matrices A and B are said to be adjacent if rank（A - B） = 1. It is proved that if φ is a bi...
