Stability conditions on morphisms in a category

چکیده
Let $\mathrm{h}\mathscr{C}$ be the homotopy category of a stable infinity $\mathscr{C}$. Then $\mathrm{h}\mathscr{C}^{\Delta^{1}}$ morphisms in $\mathscr{C}$ is also triangulated. Hence space $\mathsf{Stab}\,{ \mathrm{h}\mathscr{C}^{\Delta^{1}}}$ stability conditions on well-defined though non-emptiness not obvious. Our basic motivation comparison type $\mathsf{Stab}{\mathrm{h}\mathscr{C}}$ and that $\mathsf{Stab}{\mathrm{h}\mathscr{C}^{\Delta^{1}}}$. Under we show functors $d_{0}$ $d_{1} \colon \mathscr{C}^{\Delta^{1}} \rightrightarrows \mathscr{C}$ induce continuous maps from $\mathsf{Stab} {\mathrm{h}\mathscr{C}}$ to $\mathsf{Stab}{\mathrm{h}\mathscr{C}^{\Delta^{1}}}$ contravariantly where (resp. $d_{1}$) takes morphism target source) morphism. As consequence, if nonempty then so Assuming derived projective line over field, further study properties $d_{0}^{*} $ $d_{1}^{*}$. In addition, give an example which does have any condition.

Injectivity in a category: an overview on smallness conditions
Some of the so called smallness conditions in algebra as well as in category theory, are important and interesting for their own and also tightly related to injectivity, are essential boundedness, cogenerating set, and residual smallness. In this overview paper, we first try to refresh these smallness condition by giving the detailed proofs of the results mainly by Bernhard Banaschewski and W...

متن کاملStability of Harmonic Morphisms
We study the stability of harmonic morphisms as a subclass of harmonic maps. As a general result we show that any harmonic morphism to a manifold of dimension at least three is stable with respect to some Riemannian metric on the target. Furthermore we link the index and nullity of the composition of harmonic morphisms with the index and nullity of the composed maps.
متن کاملRelative Category Theory and Geometric Morphisms
Several logics, and types of logic, fit ill into the general framework—for example, linear logic, or relevance logic. The latter is briefly discussed in Chapter 9; Cleave dismisses the large body of work which has accumulated over the past thirty or more years, and develops his own notion of relevance, based on ' rigid formulae', those lacking 'irrelevant' subformulae, parts whose deletion (or ...
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.
