  2013 MAY 28 (VerticalNews) -- By a News Reporter-Staff News Editor at Journal of Mathematics -- Investigators discuss new findings in Discrete and Continuous Dynamical Systems. According to news reporting out of Ningxia, People's Republic of China, by VerticalNews editors, research stated, "We investigate spatiotemporal dynamics of a semi-ratio-dependent predator-prey system with reaction-diffusion and zero-flux boundary. We obtain the conditions for Hopf, Turing, and wave bifurcations of the system in a spatial domain by making use of the linear stability analysis and the bifurcation analysis. ...read more

  2013 MAY 28 (VerticalNews) -- By a News Reporter-Staff News Editor at Journal of Mathematics -- Researchers detail new data in Discrete and Continuous Dynamical Systems. According to news reporting from Auckland, New Zealand, by VerticalNews journalists, research stated, "This paper studies the optimal investment problem for an insurer in an incomplete market. The insurer's risk process is modeled by a Levy process and the insurer is supposed to have the option of investing in multiple risky assets whose price processes are described by the standard Black-Scholes model. ...read more

  2013 MAY 28 (VerticalNews) -- By a News Reporter-Staff News Editor at Journal of Mathematics -- Current study results on Discrete and Continuous Dynamical Systems have been published. According to news reporting originating from Jinan, People's Republic of China, by VerticalNews correspondents, research stated, "The objective of vehicle routing problem is usually to minimize the total traveling distance or cost. But in practice, there are a lot of problems needed to minimize the fastest completion time. ...read more
