Two Categories of 13C/12C Ratios for Higher Plants

Two Categories of 13C/12C Ratios for Higher Plants

"C/"C ratios have been determined for plant tissue from 104 species representing 60 families. Higher plants fall into two categories, those with low 5PDB "3C values (-24 to -34%o) and those with high "3C values (-6 to -19%0). Algae have 8 "C values of -12 to -23%o. Photosynthetic fractionation leading to such values is discussed. Carbon isotope fractionation is associated with photosynthesis. T...

Higher Operads, Higher Categories

AN INTRODUCTION TO HIGHER CLUSTER CATEGORIES

In this survey, we give an overview over some aspects of the set of tilting objects in an $m-$cluster category, with focus on those properties which are valid for all $m geq 1$. We focus on the following three combinatorial aspects: modeling the set of tilting objects using arcs in certain polygons, the generalized assicahedra of Fomin and Reading, and colored quiver mutation.

Steps toward the weak higher category of weak higher categories in the globular setting

We start this article by rebuilding higher operads of weak higher transformations, and correct those in cite{Cambat}. As in cite{Cambat} we propose an operadic approach for weak higher $n$-transformations, for each $ninmathbb{N}$, where such weak higher $n$-transformations are seen as algebras for specific contractible higher operads. The last chapter of this article asserts that, up to precise...
