A quasiconformal variant of the union problem
Diganta Borah, Prachi Mahajan, Kaushal Verma
The Union Problem, which has its genesis in the classical Levi problem, asks for a classification of complex manifolds that can be exhausted by an increasing union of submanifo…
Modeling the Impact of Immune Boosting on Population-Level Vaccine Effectiveness
Nir Gavish, Guy Katriel, Zohar Rom-Ramon
We extend the standard susceptible-infected-recovered framework to incorporate natural immune boosting during a short-scale outbreak. By deriving closed-form final size relations,…
Optimal regulation in a periodic environment: insights from a simple model
Nir Gavish, Guy Katriel
We perform a detailed study of a simple mathematical model addressing the problem of optimally regulating a process subject to periodic external forcing, which is interesting both…
A new oscillatory regime in two-strain epidemic models with partial cross-immunity
Nir Gavish
Infectious diseases often involve multiple strains that interact through the immune response generated after an infection. This study investigates the conditions under which a two-…
