DYNAMICS OF HOLLING-TYPE II PREY–PREDATOR SYSTEM WITH A PROTECTION ZONE FOR PREY
In this paper, a diffusive predator–prey model with Holling type II (Michaelis–Menten) functional response and a protection zone for prey is investigated. Dynamics and steady state solutions of the system are analyzed. We give the a priori estimates and obtain the nonexistence of nonconstant positive solution as the diffusion coefficients are large enough. Moreover, we demonstrate the existence and stability of nonconstant steady state solutions branching from constant semi-trivial solution by using bifurcation theory.

KRUŽNI PRAMENOVI U INVERZIVNOJ GEOMETRIJI
Kružni pramenovi sudeluju kao glavne karike u brojnim konstrukcijama koje se zasnivaju na idejama inverzivne geometrije. Na ovom predavanju ćemo prikazati konstrukciju inverzivnog kruga (engl. mid-circle) dvaju krugova hiperboličkog kružnog pramena. Posebnu pažnju ćemo posvetiti njihovoj primeni. Pokazaćemo da postoji inverzija kojom se četiri proizvoljne tačke preslikavaju u temena paralelograma.
