    • The role of uncertainty in the design of sustainable and precautionary management strategies for fisheries 
      Riquelme, Víctor; Quinn II, Terrance J.; Ramírez Cabrera, Héctor (Wiley, 2020)
      Environmental variability has a strong influence on marine fish stocks. Thus, management and harvest policies based on deterministic indicators, such as maximum sustainable yield (MSY), may be inappropriate facing such ...
    • The contact process with dynamic edges on Z 
      Linker, Amitai; Remenik Zisis, Daniel (Universidad de Washington, 2020)
      We study the contact process running in the one-dimensional lattice undergoing dynamical percolation, where edges open at rate vp and close at rate v(1-p). Our goal is to explore how the speed of the environment, v, affects ...

    • Boundary of Maximal Monotone Operators Values 
      Hantoute, Abderrahim; Nguyen, Bao Tran (Springer, 2020)
      We characterize in Hilbert spaces the boundary of the values of maximal monotone operators, by means only of the values at nearby points, which are close enough to the reference point but distinct of it. This allows to ...
