Morphisms for resistive electrical networks
This paper presents a notion of morphism for resistive electrical networks. It is obvious that symmetries of a resistive network are (trivial) morphisms and easy to show that they induce a nontrivial quotient (their symmetrizer). We extend this result to arbitrary RESNET morphisms having a common domain (called the pushout in category theory). Our principle application of RESNET morphisms is to...
متن کاملOn morphisms of crossed polymodules
In this paper, we prove that the category of crossed polymodules (i.e. crossed modules of polygroups) and their morphisms is finitely complete. We, therefore, generalize the group theoretical case of this completeness property of crossed modules.
متن کاملA Degeneration of Stable Morphisms and Relative Stable Morphisms
Let W → C be degeneration of smooth varieties so that the special fiber has normal crossing singularity. In this paper, we first constructed the stack of expanded degenerations of W . We then constructed the moduli space of stable morphisms to this stack, which provides a degeneration of the moduli spaces of stable morphisms associated to W/C. Using similar technique, for a pair of smooth varie...
متن کاملToroidalization of locally toroidal morphisms of 3-folds
A toroidalization of a dominant morphism $varphi: Xto Y$ of algebraic varieties over a field of characteristic zero is a toroidal lifting of $varphi$ obtained by performing sequences of blow ups of nonsingular subvarieties above $X$ and $Y$. We give a proof of toroidalization of locally toroidal morphisms of 3-folds.
متن کاملMorphisms of polar spaces
Polar spaces are presented from the point of view of paraprojective spaces. Morphisms are introduced and some immediate categorical aspects are reviewed. The morphisms of polar spaces are then studied in more details and are shown to preserve the spaces’ structure. Finally, it is shown that a morphism of polar spaces can be split into a morphism of nondegenerate polar spaces and a morphism of p...
