Introducing the critical exponent $sigma^* := 2(1-q)/(m-1)$ for $m > 1$ and $sigma^*=infty$ for $m=1$, extinction in finite time is known to take place for $sigmain [0,sigma^*)$ and an alternative proof is provided therein. When $m > 1$ and $sigmage sigma^*$, the occurrence of finite time extinction is proved for a specific class of initial conditions, thereby supplementing results on non-extinction that are available in that range of $sigma$ and showing their sharpness.","PeriodicalId":50581,"journal":{"name":"Differential and Integral Equations","volume":"21 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136103064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
