    Homeomorphisms of Compact Sets in Certain Hausdorff Spaces by Arthur D. Grainger

    Published 2011-01-01
    “…We construct a class of Hausdorff spaces (compact and noncompact) with the property that nonempty compact subsets of these spaces that have the same cardinality are homeomorphic. Also, it is shown that these spaces contain compact subsets that are infinite.…”

    On the Structure of Brouwer Homeomorphisms Embeddable in a Flow by Zbigniew Leśniak

    Published 2012-01-01
    “…We present two theorems describing the structure of the set of all regular points and the set of all irregular points for a Brouwer homeomorphism which is embeddable in a flow. The theorems are counterparts of structure theorems proved by Homma and Terasaka. …”

    Solutions for m-Point BVP with Sign Changing Nonlinearity by Hua Su

    Published 2009-01-01
    “…We study the existence of positive solutions for the following nonlinear m-point boundary value problem for an increasing homeomorphism and homomorphism with sign changing nonlinearity: {(ϕ(u′(t)))′+a(t)f(t,u(t))=0, 0<t<1, u′(0)=∑i=1m−2aiu′(ξi), u(1)=∑i=1kbiu(ξi)−∑i=k+1sbiu(ξi)−∑i=s+1m−2biu′(ξi), where ϕ:R→R is an increasing homeomorphism and homomorphism and ϕ(0)=0. …”

    Arcwise Connected Domains, Quasiconformal Mappings, and Quasidisks by Yu-Ming Chu

    Published 2014-01-01
    “…We prove that a homeomorphism f:R2→R2 is a quasiconformal mapping if and only if f(D) is an arcwise connected domain for any arcwise connected domain D⊆R2, and D is a quasidisk if and only if both D and its exterior D*=R2∖D¯ are arcwise connected domains.…”

    Stability Analysis of Cohen–Grossberg Type BAM Neural Network with Piecewise Constant Argument by Wenqing Zheng, Tao Xie, Wenxiang Fang

    Published 2023-01-01
    “…This paper introduces the stability problems of Cohen–Grossberg type BAM neural network (BAMCGNN) with piecewise constant argument (PCA). By employing the homeomorphism theory, sufficient conditions for the existence and uniqueness of the equilibrium point are obtained; using inequality technique and Lyapunov method, sufficient stability criteria for BAMCGNN with PCA are presented. …”
