Similarity Orders from Causal Equations

The purpose of this paper is to demonstrate that, contrary to the received wisdom, causal reasoning can be formalized wholly within the framework of Lewis’ conditional logic. To this aim we simulate causal reasoning based on structural equations in Lewis’ order semantics. This reduction is based on a formalization of an intuitive idea for computing relative similarity between worlds. Worlds are...

Causal Ambiguity and Partial Orders in Event Structures

Event structure models often have some constraint which ensures that for each system run it is clear what are the causal predecessors of an event (i.e. there is no causal ambiguity). In this contribution we study what happens if we remove such constraints. We de ne ve di erent partial order semantics that are intentional in the sense that they refer to syntactic aspects of the model. We also de...

Quantum quenches and competing orders

Abstract We study the non-equlibrium dynamics of an electronic model of competition between an unconventional charge density wave (a bond density wave) and d-wave superconductivity. In a time-dependent HartreeFock+BCS approximation, the dynamics reduces to the equations of motion of operators realizing the generators of SU(4) at each pair of momenta, (k, k), in the Brillouin zone. We also study...

Maximum Distance Between Slater Orders and Copeland Orders of Tournaments

Given a tournament T = (X, A), we consider two tournament solutions applied to T: Slater’s solution and Copeland’s solution. Slater’s solution consists in determining the linear orders obtained by reversing a minimum number of directed edges of T in order to make T transitive. Copeland’s solution applied to T ranks the vertices of T according to their decreasing out-degrees. The aim of this pap...

Distinguishing Causal and Acausal Temporal Relations

In this paper we propose a solution to the problem of distinguishing between causal and acausal temporal sets of rules. The method, called the Temporal Investigation Method for Enregistered Record Sequences (TIMERS), is explained and introduced formally. The input to TIMERS consists of a sequence of records, where each record is observed at regular intervals. Sets of rules are generated from th...
