Morphisms and Inverse Problems
In order to investigate polynomial vector fields admitting a prescribed Darboux integrating factor, we show that it is helpful to employ morphisms of the affine plane. In particular, such morphisms may be used to remove degeneracies of the underlying curve. Our main result states that the space of vector fields admitting a prescribed Darboux integrating factor modulo a well understood subspace ...
متن کاملMorphisms for Semi–dynamical Systems
Introduction. The semi–dynamical systems were introduced in the framework of the axiomatic potential theory by H m i s s i [5] and, in the more general form used in this note, by B u c u r – B e z z a r g a [1], [2]. The present paper is a natural continuation of [8] and represents the printed form of the technical report [9]. The notion of morphism was introduced in potential theory in [6], se...
متن کاملMorphisms and Inverse Problems for Darboux Integrating Factors
Polynomial vector fields which admit a prescribed Darboux integrating factor are quite well-understood when the geometry of the underlying curve is nondegenerate. In the general setting morphisms of the affine plane may remove degeneracies of the curve, and thus allow more structural insight. In the present paper we establish some properties of integrating factors subjected to morphisms, and we...
متن کاملCategory of asynchronous systems and polygonal morphisms
A weak asynchronous system is a trace monoid with a partial action on a set. A polygonal morphism between weak asynchronous systems commutes with the actions and preserves the independence of events. We prove that the category of weak asynchronous systems and polygonal mor-phisms has all limits and colimits.
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.
