【摘要】：本文對(duì)于一類分布于一維空間并帶自由邊界的捕食模型的初邊值問題,研究捕食者與被捕食者的長(zhǎng)時(shí)間發(fā)展行為.首先,給出發(fā)展-滅亡二分法,我們研究當(dāng)t→∞時(shí),兩物種或者得到成功的發(fā)展,從而在新的環(huán)境下成功生存下去；或者發(fā)展失敗,一段時(shí)間后滅亡.其次,給出了兩物種發(fā)展-滅亡的準(zhǔn)則.最后,我們研究當(dāng)物種能夠得到成功發(fā)展時(shí),給出其發(fā)展速度的一個(gè)估計(jì).
[Abstract]:In this paper, the behavior of predator and predator over a long period of time is studied for the initial boundary value problem of a predator model with free boundary in one-dimensional space. First of all, we give the development-perishing dichotomy, we study that when t 鈭，
