It is thus understood that the issue at hand can be approached from a variety of viewpoints and aspects, such as the philosophical, psychological, psychoanalytical, technological, neurophysiologieal, sociological, literary and so on Our viewpoint is strictly limited to the theatrical dimension and our analysis will prosress based on data comprising the theatrical phenomenon, that is, the illusion, as opposed to virtual reality of modern technology.展开更多

Compact simplicial toric varieties are in our family. For a prime number p, the authors find a necessary condition for the integral cohomology of X to have no p-torsion. Then it is proved that the necessary condition is sufficient in some cases. The authors also give an example of X which shows that the necessary condition is not sufficient in general.展开更多
