BOUNDEDNESS AND EXPONENTIAL STABILIZATION IN A PARABOLIC-ELLIPTIC KELLER–SEGEL MODEL WITH SIGNAL-DEPENDENT MOTILITIES FOR LOCAL SENSING CHEMOTAXIS被引量：1
《Acta Mathematica Scientia》2022年第3期825-846,共22页Jie JIANG 
supported by Hubei Provincial Natural Science Foundation(2020CFB602).
In this paper we consider the initial Neumann boundary value problem for a degenerate Keller-Segel model which features a signal-dependent non-increasing motility function.The main obstacle of analysis comes from the ...

ON THE EXISTENCE WITH EXPONENTIAL DECAY AND THE BLOW-UP OF SOLUTIONS FOR COUPLED SYSTEMS OF SEMI-LINEAR CORNER-DEGENERATE PARABOLIC EQUATIONS WITH SINGULAR POTENTIALS
《Acta Mathematica Scientia》2021年第1期257-282,共26页Hua CHEN Nian LIU 
supported by NFSC(11871387 and 11931012)。
In this article,we study the initial boundary value problem of coupled semi-linear degenerate parabolic equations with a singular potential term on manifolds with corner singularities.Firstly,we introduce the corner t...

POSITIVE STEADY STATES AND DYNAMICS FOR A DIFFUSIVE PREDATOR-PREY SYSTEM WITH A DEGENERACY被引量：2
《Acta Mathematica Scientia》2016年第2期537-548,共12页杨璐 张贻民 
supported by the National Natural Science Foundation of China(11361053,11201204,11471148,11471330,145RJZA112)
In this article, we consider positive steady state solutions and dynamics for a spatially heterogeneous predator-prey system with modified Leslie-Gower and Holling-Type II schemes. The heterogeneity here is created by...

A DEGENERACY THEOREM FOR MEROMORPHIC MAPPINGS WITH TRUNCATED MULTIPLICITIES被引量：2
《Acta Mathematica Scientia》2011年第2期549-560,共12页颜启明 陈志华 
supported by the National Natural Science Foundation of China(10871145, 10901120);Doctoral Program Foundation of the Ministry of Education of China (20090072110053)
In this article, we prove a degeneracy theorem for three linearly non-degenerate meromorphic mappings from Cn into PN （C）, sharing 2N ＋ 2 hyperplanes in general position, counted with multiplicities truncated by 2.

PARABOLIC　EQUATIONS　WITH　BOTH　NON－CONVEXITY　NONLINEARITIES　AND　STRONG　DEGENERACY被引量：1
《Acta Mathematica Scientia》1994年第4期451-460,共10页尹景学 
This paper is devoted to a strongly degenerate or singular quasilinear parabolic equation.We first extend Kalashnikov's ekistence results [6] to a general situation for the equation without convexity. As a supplementa...
