Discrete May-leonard Competition Models Ii
We analyzed the local dynamics of a three-dimensional Ricker type discrete-time competition model that is analogous to the May-Leonard (M-L) differential equation model. The symmetric discrete M-L model is mentioned by Hofbauer et al. [7, J. Math. Biol., 25:553–570,1987] as “perhaps one of the most difficult three species problems”. Both of the discrete and the continuous M-L models have simila...
متن کاملQuality Sensitive Price Competition in Spectrum Oligopoly: Part II
We investigate a spectrum oligopoly market where each primary seeks to sell its idle channel to a secondary. Transmission rate of a channel evolves randomly. Each primary needs to select a price depending on the transmission rate of its channel. Each secondary selects a channel depending on the price and the transmission rate of the channel. We formulate the above problem as a non-cooperative g...
متن کاملCentral Path Dynamics and a Model of Competition. II
Growth – the change in number or size – and adaptation – the change in quality or structure – are key attributes of global processes in natural communities, society and economics (see, e.g., Hofbauer and Sigmund, 1988; Freedman, 1991; Young, 1993). In this paper we describe a model with explicit growth-adaptation feedbacks. We treat it in the form of an economic model of competition of two firm...
متن کاملCompetition hypergraphs of digraphs with certain properties II. Hamiltonicity
If D = (V,A) is a digraph, its competition hypergraph CH(D) has vertex set V and e ⊆ V is an edge of CH(D) iff |e| ≥ 2 and there is a vertex v ∈ V , such that e = N− D (v) = {w ∈ V |(w, v) ∈ A}. We give characterizations of CH(D) in case of hamiltonian digraphs D and, more general, of digraphs D having a τ -cycle factor. The results are closely related to the corresponding investigations for co...
متن کاملObstacle Avoidance Wheelchair System Submission to CanestaVisionTM Competition: Phase II
We present a collision avoidance system for powered wheelchairs used by people with cognitive disabilities. Such systems increase mobility and feelings of independence, thereby enabling reversal of some symptoms of depression and cognitive impairment and improvement of quality of life. Canesta electronic perception technology allows the wheelchair to “see” obstacles, avoid collisions, and sugge...
