著作名稱:S-shaped and broken S-shaped bifurcation curves for a multiparameter diffusive logistic problem with Holling type-III functional response
年度:2017
類別:期刊論文
摘要:We study exact multiplicity and bifurcation curves of positive solutions for a multiparameter diffusive logistic problem with Holling type-III functional response. We give a classification of four qualitatively different bifurcation curves: an S-shaped curve, a broken S-shaped curve, a ⊂-shaped curve and a monotone increasing curve.

著作名稱:Classification of bifurcation diagrams for a multiparameter diffusive logistic problem with Holling type-IV functional response
年度:2014
類別:期刊論文
摘要:We study exact multiplicity and bifurcation diagrams of positive solutions for a multiparameter diffusive logistic problem with Holling type-IV functional response. Under some assumptions, we give a classification of four qualitatively different bifurcation diagrams: an S-shaped curve, a broken S-shaped curve, a ㄈ-shaped curve and a monotone increasing curve.

著作名稱:Classification of bifurcation diagrams of a p-Laplacian nonpositone problem
年度:2013
類別:期刊論文
摘要:We study the bifurcation diagrams of positive solutions of a p-Laplacian Dirichlet problem. Under certain hypotheses, we give a complete classification of bifurcation diagrams. We prove that, each bifurcation diagram consists of exactly one curve which has exactly one turning point where the curve turns to the right. In addition, we show the evolution phenomena of bifurcation diagrams of polynomial nonlinearities with positive coefficients.

著作名稱:S-shaped and broken S-shaped bifurcation diagrams with hysteresis for a multiparameter spruce budworm population problem in one space dimension
年度:2013
類別:期刊論文
摘要:We study exact multiplicity and bifurcation diagrams of positive solutions for a multiparameter spruce budworm population steady-state problem in one space dimension. We give a classification of three qualitatively different bifurcation diagrams: an S-shaped curve, a broken S-shaped curve, and a monotone increasing curve. Our results settle rigorously a long-standing open problem in Ludwig, Aronson and Weinberger (J. Math. Biol., 8 (1979), pp. 217258).
