Given a closed Riemannian manifold (M, g), i.e. compact and boundaryless, there is a partition of its tangent bundle TM = ∪iΣi called the focal decomposition of TM. The sets Σi are closely associated to focusing of geodesics of (M, g), i.e. to th

The rigidity conjecture

A central question in dynamics is whether the topology of a system determines its geometry. This is known as rigidity. Under mild topological conditions rigidity holds for many classical cases, including: Kleinian groups, circle diffeomorphisms, unim

Newhouse Laminations of polynomials on ℂ2

It has been recently discovered that in smooth unfoldings of maps with a rank-one homoclinic tangency there are codimension two laminations of maps with infinitely many sinks. Indeed, these laminations, called Newhouse laminations, occur also in the

In this paper we present a new method for simulating and mapping energy demands for European museums for recent past (RP), near future 2020-2050 (NF) and far future 2070-2100 (FF). It is new combination of three recent developments: Firstly, the simu

Museums are dedicated to protect their artwork collection and to display the collection as safely as possible. Amongst other things, the indoor climate is of utmost importance to minimize collection degradation. Many museums employ tight climate guid
