Model topoi and motivic homotopy theory
Georgios Raptis, Florian Strunk
Given a small simplicial category $\C$ whose underlying ordinary category is equipped with a Grothendieck topology , we construct a model structure on the category of simplicial…
Small presentations of model categories and Vopěnka's principle
G. Raptis, J. Rosický
We prove existence results for small presentations of model categories generalizing a theorem of D. Dugger from combinatorial model categories to more general model categories. Som…
The realization space of an unstable coalgebra
Georg Biedermann, Georgios Raptis, Manfred Stelzer
Unstable coalgebras over the Steenrod algebra form a natural target category for singular homology with prime field coefficients. The realization problem asks whether an unstable c…
K-theory of derivators revisited
Fernando Muro, George Raptis
We define a -theory for pointed right derivators and show that it agrees with Waldhausen -theory in the case where the derivator arises from a good Waldhausen category. This…
Quantum Chrono-Topology of Nuclear and Sub-Nuclear Reactions
C. Syros, C. Schulz-Mirbach
A quantum time topological space is developed and applied to solve some problems about quantum theory. It is disconnected and satifies specific separation axioms. The degree of dis…
