借助奇点理论对光滑函数芽(单变量分支问题)在强接触等价群作用下的分类,研究了一类非线性二阶系统边值分支解的存在性和分支解的个数等问题.在一定条件下给出了这类系统的平衡解的局部分支性态,包括分支解的存在性和分支解的个数.
Using singularity theory for classifiying smooth germs of function under the action of strong contact equivalence group, problems concerning the existence and number of bifurcation solution of a class of 2nd-order nonlinear system are studied. The result gives the local bifurcation properties of equilibrium solution of this system, including the information of the existence and the number of the bifurcation solutions.
