Chimera States in a Two-Population Network of Coupled Pendulum-Like Elements
More than a decade ago, a surprising coexistence of synchronous and
asynchronous behavior called the chimera state was discovered in networks of
nonlocally coupled identical phase oscillators. In later years, chimeras were
found to occur in a variety of theoretical and experimental studies of chemical
and optical systems, as well as models of neuron dynamics. In this work, we
study two coupled populations of pendulum-like elements represented by phase
oscillators with a second derivative term multiplied by a mass parameter
and treat the first order derivative terms as dissipation with parameter
. We first present numerical evidence showing that chimeras do
exist in this system for small mass values . We then proceed to explain
these states by reducing the coherent population to a single damped pendulum
equation driven parametrically by oscillating averaged quantities related to
the incoherent population

Uniformly starlike and uniformly convex mappings in several complex variables
In this paper we introduce some subclasses of biholomorphic mappings on the unit ball of â„‚ n. These mappings called uniformly starlike and uniformly convex are introduced by geometric interpretation, like in the case of one variable
