Projective Bundles and Blowing-Ups Ⅱ
《Algebra Colloquium》2024年第1期57-62,共6页Duo Li 
supported by National Natural Science Foundation of China(12001547);Guangdong Basic and Applied Basic Research Foundation(2019A1515110907).
We study the blowing-up X of a smooth projective variety X along a smooth center B that is equipped with a projective bundle structure over a variety Z.If the Picard number p(X)is 1 and dim X is at most 4,we classify ...

Asymptotic Behavior of Solutions to a Class of Semilinear Parabolic Equations with Boundary Degeneracy
《Communications in Mathematical Research》2023年第1期54-78,共25页Xinxin Jing Chunpeng Wang Mingjun Zhou 
This work was supported by the National Key R&D Program of China(Grant No.2020YFA0714i01);by the National Natural Science Foundation of China(Grant No.11925105).
This paper concerns the asymptotic behavior of solutions to one-dimensional semilinear parabolic equations with boundary degeneracy both in bounded and unbounded intervals.For the problem in a bounded inter-val,it is ...

On the Two Methods for Finding 4-Dimensional Duck Solutions
《Applied Mathematics》2014年第1期16-24,共9页Kiyoyuki Tchizawa 
This paper gives the existence of a duck solution in a slow-fast system in R2+2 using two ways. One is an indirect way and the other is a direct way. In the indirect way, the original system is once reduced to the slo...

Blowing-ups and Valuations on Surfaces
《Acta Mathematica Sinica,English Series》2011年第7期1305-1314,共10页Ning XU 
In this paper, we show that all the nontrivial valuations on surfaces can be given by the infinite sequences of blowing-ups, and give the process of blowing-ups.

The Blowing-up of the Solutions for a Class of Nonlinear Reaction-Diffusion Equations
《Systems Science and Systems Engineering》1999年第4期9-12,共4页YAN Gui\|qing Department of Mathematics and Information Science, Yantai University Yantai 264005,China 
In this paper, we discuss the blowing\|up of the solutions of a class of nonlinear reaction\|diffusion equations with the general (or nonlinear) boundary conditions. On some proper assumptions, we conclude that there ...

On the Blowing-up Behaviours for Nonlirear Wave Equations被引量：5
《Chinese Quarterly Journal of Mathematics》1992年第1期11-17,共7页张健 
This paper deals with the initial-boundary value mixed problems for nonlinear wave equations. By introducing the 'blowing-up facts K(u,u_i)', We may discuss the blowing up behaviours of solutions in finite time to the...
