The event bush is a new method of artificial intelligence proposed specially to meet the needs of geosciences, from basic research to communication with nonprofessionals. First results of its application as well as combination of event bush with mathematical and logical formalisms are encouraging, and the method has shown some advantages to existing approaches, as well as an ability to unite th...

We consider a finite set of lattice points and their convex hull. The author previously gave a geometric proof that the sumsets of these lattice points take over the central regions of dilated convex hulls, thus revealing an interesting connection between additive number theory and geometry. In this paper, we will see an algebraic proof of this fact when the convex hull of points is a simplex, ...

Affectionately dedicated to Mel Hochster, who has been an inspiration to us for many years, on the occasion of his 65th birthday. Abstract We study the fibers of projective morphisms and rational maps. We characterize the analytic spread of a homogeneous ideal through properties of its syzygy matrix. Powers of linearly presented ideals need not be linearly presented, but we identify a weaker li...
