讨论了2维Zakharov方程组的Caucgy问题的爆破解.对径向对称爆破解,证明了原点0是爆破点,并建立了当t→T(爆破时间)时,集中率的下界.
This paper considers the Cauchy problem of the Zakharov equations in R2. For the radially symmetric blow-up solutions, it is proved that the origin 0 is a blow-up point and the rate of L^2-concentration as t → T (blow-up time) is obtained.
