A bstract We consider the cosmology obtained using scalar fields with a negative potential energy, such as employed to obtain an Ekpyrotic phase of contraction. Applying covariant entropy bound tower states dictated by distance conjecture, we find that relative slope | V ′|/| is bounded from below constant order one in Planck units. This consistent requirement slow also derive refined condition...

In the context of a canonical agency model, we study payoff implications introducing optimally structured incentives. We do so from perspective an analyst who does not know agent's preferences for responding to incentives, but that principal knows them. provide, in particular, tight bounds on principal's expected benefit optimal incentive contracting across feasible values rents. thus show how ...

Let G $G$ be a finitely generated group. We show that for any finite symmetric generating set A $A$ , the language consisting of all geodesics in Cay ( ) $(G,A)$ with contracting property is regular language. An immediate consequence existence an infinite geodesic Cayley graph group implies element. In particular, torsion groups cannot contain geodesic. As application, this containing must eith...

Abstract Die Chemiebranche steht vor großen Herausforderungen, um die Kohlendioxidemissionen zu reduzieren und Produktion Decarbonisieren. Lösung liegt im Einsatz grüner Moleküle dafür notwendige zusätzliche “Fabrik der Fabrik” wird zum entscheidenden Erfolgsfaktor für Energiewende. Entsprechende Konzepte entstehen aktuell bei Getec in Schweiz den Niederlanden
