运用二维系统定性理论,研究一类二维Lotka-Volterra竞争系统在有限时间内的持续生存与绝灭问题,即β持续生存与β绝灭。
運用二維繫統定性理論,研究一類二維Lotka-Volterra競爭繫統在有限時間內的持續生存與絕滅問題,即β持續生存與β絕滅。
운용이유계통정성이론,연구일류이유Lotka-Volterra경쟁계통재유한시간내적지속생존여절멸문제,즉β지속생존여β절멸。
By two-dimensional system qualitative theory,this paper discusses the problem of the sustained existence and extermination of two-dimensional Lotka-Volterra competitional system in limited time,which means the problem of β sustained existence and β extermination.
