Gotzmann Edge Ideals
Andrew H. Hoefel
Let P = k[x_1, ..., x_n] be the polynomial ring in n variables. A homogeneous ideal I of P generated in degree d is called Gotzmann if it has the smallest possible Hilbert function…
Properties of kinematic singularities
A. A. Coley, S. Hervik, W. C. Lim +1
The locally rotationally symmetric tilted perfect fluid Bianchi type V cosmological model provides examples of future geodesically complete spacetimes that admit a `kinematic singu…
Lorentzian spacetimes with constant curvature invariants in four dimensions
Alan Coley, Sigbjorn Hervik, Nicos Pelavas
In this paper we investigate four dimensional Lorentzian spacetimes with constant curvature invariants ( spacetimes). We prove that if a four dimensional spacetime is , t…
Incorporating uncertainty into the study of animal social networks
David Lusseau, Hal Whitehead, Shane Gero
Over the past decade network theory has been applied successfully to the study of a variety of complex adaptive systems. However, the application of these techniques to non-human s…
Effects of external global noise on the catalytic CO oxidation on Pt(110)
P. S. Bodega, S. Alonso, H. H. Rotermund
Oxidation reaction of CO on a single platinum crystal is a reaction-diffusion system that may exhibit bistable, excitable, and oscillatory behavior. We studied the effect of a stoc…
Spacetimes characterized by their scalar curvature invariants
Alan Coley, Sigbjorn Hervik, Nicos Pelavas
In this paper we determine the class of four-dimensional Lorentzian manifolds that can be completely characterized by the scalar polynomial curvature invariants constructed from th…
