Let f(z) = z +az + bz + cz+ d ∈ Z[z] and let us consider a del Pezzo surface of degree one given by the equation Ef : x 2 − y − f(z) = 0. In this note we prove that if the set of rational points on the curve Ea, b : Y 2 = X + 135(2a − 15)X − 1350(5a + 2b − 26) is infinite, then the set of rational points on the surface Ef is dense in the Zariski topology.

The CELEBRATEproject developed and successfully demonstrated a federated learning object brokerage system architecture and made available to schools over 1350 learning objects produced by both public and private sector content developers. Despite its encouraging results in terms of acceptance by the participating teachers and pupils, some of the assumptions the technical infrastructure was orig...

Some recent studies have investigated the scale and scope of a remarkable series of late classic prehistoric (est. 1350 CE) water management structures found in Arizona’s upper Gila Valley. These canal systems are characterized by their being literally "hung" on the edges of steep sided, gently sloping mesas formed from remnant Quaternary age bajadas. The mesas today will appear characteristica...
