In logical theories of change it is common to consider two types of objects that provoke change: 1) actions that are carried out by agents, and 2) events which occur externally, without agent intervention. In this paper we argue for the existence of a special type of event, which we call natural events. An event is called natural if its occurrence is the result of a natural process. For example...

In one stream of development, one partner in the project had just achieved an interpretation of group cohomology or Lie-algebra cohomology in terms of higher-dimensional central extensions, as developed by Rodelo–Van der Linden [14, 15]. It extends the classical interpretation of the second group cohomology in terms of equivalence classes of short exact sequences with central kernel. This devel...

We give a rigorous proof of existence for solitary waves of a peridynamics model in one space dimension recently investigated by Silling (J. Mech. Phys. Solids 96:121–132, 2016). We adapt the variational framework developed by Friesecke and Wattis (Comm. Math Phys. 161:391–418, 1994) for the FermiPasta-Ulam-Tsingou lattice equations to treat a truncated problem which cuts off short-range intera...
