Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

首先，讨论了R~2中一类带不定权且含临界位势的二阶椭圆型方程的特征值问题，并借此特征值问题的第一特征值性质，利用山路引理及Trudinger-Moser不等式，证明了R~2中一类带不定权且含临界位势的非线性椭圆型方程非平凡解的存在性；其次，利用广义环绕定理，Trudinger-Moser不等式及集中列紧原理，得到了R~2上一类具有强不定部分的半线性椭圆型方程组在非线性项分别为次临界增长和临界增长情形下非平凡解的存在性。

Secondly, we study a class of automorphisms of A, i.e., we prove that the set {φ∈SL_n|φ= t is a subgroup of AutA(n,t,Finally, we mainly discuss some properties of the operation w in A, i.e., g~w = 0, f~w = 0 and Leibniz identity.

其次，讨论了A的一类自同构，即证明了集合{φ∈SL_n|φ=t}是自同构群AutA(n，t的一个子群；最后，得到了A的运算w的一些性质，即g~w=0、f~w=0和Leibniz等式。

HE GAVE A PROFESSIONAL COMMENT ON THE NEW CAR.Although Eric is fond of big cars, as a matter of fact, the new C-Class is very familiar to him. Without the introduction of the writer, he gave a lot of opinion about C-280 Avantgarde. When compared with the old model, the new C-Class is much more sporty and does not lack the sense of grandeur which a Mercedes Benz has. Besides, its space is big enough and is suitable for the whole family.

虽然Eric钟情大型车，原来他对新C-Class亦耳熟能详，毋须笔者介绍，已经大谈他对C280 Avantgarde的意见，「新C-Class的设计，比起旧款实在Sporty得多，又不失平治的豪华感，加上空间够大，一家大小使用亦可，年轻人一个人驾驶也适合。
