The Ne Plus Ultra of Tree Graph Inequalities*

With nary mention of a tree graph, we obtain a cluster expansion bound that includes and vastly generalizes bounds as obtained by extant tree graph inequalities. This includes applications to both two-body and many-body potential situations of the recently obtained 'new improved tree graph inequalities" that have led to the 'extra I/N! factors'. We work in a formalism coupling a discrete set of...

Rien ne Va Plus? Distinguishing domestic regulation from market access in GATT and GATS

Depending on how one classifies market intervention, trade liberalization disciplines can be lenient or strict. Perhaps the most important distinction in this respect is that between government intervention labeled as a ‘market access restriction’ and that defined as ‘domestic regulation’. Both the GATT and the GATS declare market access restrictions (such as import quotas or limitations on the...

Je vous prie, Monsieur, de vouloir bien énoncer, dans votre recueil, le théorème suivant, que je crois vrai, bien que je n’aie pas encore réussi à le démontrer complètement: d’autres seront peut-être plus heureux : Deux nombres entiers consécutifs, autres que 8 et 9, ne peuvent être des puissances exactes ; autrement dit : l’équation x − y = 1, dans laquelle les inconnues sont entières et posit...

The Mid - Infrared [ S iv ] / [ Ne ii ] versus [ Ne iii ] / [ Ne ii ] Correlation

The mid-infrared ratio [Ne iii]15.6μm/[Ne ii]12.8μm is a strong diagnostic of the ionization state of emission line objects, due to its use of only strong neon emission lines only weakly affected by extinction. However this ratio is not available to ground-based telescopes as only a few spectroscopic windows are available in the MIR. To deal with this problem we aimed to verify if there exists ...
