Analytic integrability of the Bianchi class A cosmological models with O~ 1< < 1
Elsevier (2013-03)Many works study the integrability of the Bianchi class A cosmologies with k = 1, where k is the ratio between the pressure and the energy density of the matter. Here we characterize the analytic integrability of the Bianchi ... -
Fractal generalized zone plates
Optical Society of America (2009)The construction of fractal generalized zone plates (FraGZPs) from a set of periodic diffractive optical elements with circular symmetry is proposed. This allows us to increase the number of foci of a conventional fractal ...
