Methods in Human Growth Geneticse density with the distance as a power law (the de Vaucouleurs’ density power law), the fractal dimension within the range 1 ≤ . ≤ 2, and the present range of uncertainty for the Hubble constant. The spatially homogeneous Friedmann model is discussed as a special case of the Tolman solution, and it

Introduction to Dynamical Systemserence for these proceedings. The qualitative behaviour of both linear and non-linear autonomous differential equations is discussed. Particular attention is given to Liapunov stability theory, periodic orbits, limit sets, structural stability, and bifurcation theory, leading up to higher order syst

On Defining Chaos in the Absence of Timee of initial values. Using the recent discovery that the sensitivity hypothesis is a logical consequence of the other two conditions we formulate a time-and-metric independent concept of chaos for foliations which implies the usual definition when the leaves are the orbits of a flow on a manifold. S

Chaos in the Case of Two Fixed Black Holesnate either at the black holes .. and .. (types (I) and (II)), or at infinity (type (III)). The limits of these three types of orbits are Cantor sets, defined by the unstable periodic orbits, that form a set of measure zero. In the case of particles with elliptic energy there are some stable periodi
