Under the assumption that these systems have two stable equilibrium states, F±, the multiple existence and stability of travelling wave solutions connecting P_ with P+ are shown by using analytical singular perturbation method and the SLEP method. Velocity of a travelling wave solution surely depends on the third species. For the multiple existence of stable solutions, the dependency of its velocity on the third species is important.","PeriodicalId":359486,"journal":{"name":"Mathematics journal of Toyama University","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122148110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
