  1. In chapter 3, 1 consider the nonlinear parabolic equation : where a bounded domain with smooth boundary in ; v is outward normal vector on is a positive function satisfying some compatibility conditions focus my attention on the case of m > 1, to obtain the blow - up conditions of the positive solution using the method of subsolution and supersolution

    運用緊致性原理及moser迭代得到了解的整體存在性和解的熄滅性質。第三章討論了如下形式的非線性拋物方程:其中m , , 0 , r ~ + ,為r ~ n ( n 1 )中的有界域,具有適當光滑的邊界( ? ) ; v是(
  2. Then i consider a correlative problem : where m, > 0, s is a bounded domain with smooth boundary in ; v is outward normal vector on ; f ( s ) is continuous function and satisfies some increasing conditions ; u0 ( x ) is a positive function satisfying some compatibility conditions, to obtain the blow - up conditions of the positive solution using the method of subsolution and supersolution, extend the result of song and zheng

    )上的單位外法向; u _ 0 ( x )是正的函數且滿足一定的相容性條件:討論m 1的情況時,在何種條件下使得問題的正解整體存在或是在有限時刻爆破。主要採用上下解的方法來得到結論。隨后考慮相關問題:其中m , 0 ,為r ~ n ( n 1 )中的有界域,具有適當光滑的邊界(
