Sequent and Hypersequent Calculi for Abelian and Lukasiewicz Logics
G. Metcalfe, N. Olivetti, D. Gabbay
We present two embeddings of infinite-valued Lukasiewicz logic L into Meyer and Slaney's abelian logic A, the logic of lattice-ordered abelian groups. We give new analytic proof sy…
Equivalence of driven and ageing fluctuation-dissipation relations in the trap model
Suzanne Fielding, Peter Sollich
We study the non-equilibrium version of the fluctuation dissipation (FD) relation in the glass phase of a trap model that is driven into a non-equilibrium steady state by external…
Glassy dynamics of kinetically constrained models
Felix Ritort, Peter Sollich
We review the use of kinetically constrained models (KCMs) for the study of dynamics in glassy systems. The characteristic feature of KCMs is that they have trivial, often non-inte…
Impact of Low-Energy Constraints on Lorentz Violation
J. Ellis, E. Gravanis, N. E. Mavromatos +1
We extend previous analyses of the violation of Lorentz invariance induced in a non-critical string model of quantum space-time foam, discussing the propagation of low-energy parti…
Refined and l-adic Euler characteristics of nearly perfect complexes
David Burns, Bernhard Köck, Victor Snaith
We lift the Euler characteristic of a nearly perfect complex to a relative algebraic K-group by passing to its l-adic Euler characteristics.
