El aprendizaje, entendido en su sentido más amplio como el desarrollo de competencias y destrezas todo tipo (personales académicas, técnicas, profesionales…) se produce distintos contextos —formales, no formales, informales— siempre con la premisa atención e interés quien aprende. No hay dos personas iguales y, por tanto, formas aprender. ¿Por qué nos empeñamos enseñar una manera estandarizada ...

developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...

Abstract We provide foundations for a characteristic free study of foliated varieties in terms infinitesimal actions formal groupoids. The ultimate goal is the bi-rational geometry same, and to this end we prove cone theorem foliations curves, together with structure theorems extremal rays, and, course, minimal model surfaces. All possible wild ramification effects Deligne–Mumford champ are bui...
