THE TRANSITION FROM the Mesolithic to the Early Neolithic in the western Mediterranean is a stimulating subject for more than one reason. First, the region’s geographic position means that it is a case of ‘distant Neolithisation’ (between 2000–3500 km) from the presumed epicentre of Neolithisation in south-east Asia, around the Turko-Syrian border. Attempting to grasp the economic, social or sy...

In this paper we present a survey of the use of differential geometric formalisms to describe Quantum Mechanics. We analyze Schrödinger and Heisenberg frameworks from this perspective and discuss how the momentum map associated to the action of the unitary group on the Hilbert space allows to relate both approaches. We also study Weyl-Wigner approach to Quantum Mechanics and discuss the implica...

INTRODUCTION A 20% of world cycad species are found in Mexico, 80% of which are endemic (Vovides, 2000). At least nine species are present in the state of San Luis Potosí: Dioon edule, Zamia fi scheri, Z. loddigesii, Ceratozamia hildae, C. kuesteriana, C. latifolia, C. mexicana, C. microstrobila, and C. zaragozae (Yáñez-Espinosa, 2006) [Ed’s note: Zamia vazquezii is also found in San Luis Potos...
