Ever since the appearance of renormalization theory there have been several differently motivated attempts at nonlocalized (in the sense of not generated by pointlike fields) relativistic particle theories, the most recent one being at QFT on noncommutative Minkowski spacetime. The often conceptually uncritical and historically forgetful contemporary approach to these problems calls for a critical review in the light of previous results on this subject. 1 History of attempts at nonlocal fields To attribute indepth investigations of nonlocal QFT to the last decade, as it is done in most contemporary articles on this subject, is historically incorrect. There was already a flurry of interest (quite a strong one considering the number of particle physicist at that time) in nonlocal aspects of QFT leading to significant results as far back as the late 50s 1. This interest originated in the wake of renormalization of QED and of the LSZ scattering theory. The main

mulated the problem, analyzed it, and presented computations. In this second part, we first give a weak formulation of the problem, carefully contrived so that the pressure boundary terms are eliminated from the equations. We prove that the bilinear forms appearing in the weak formulation satisfy continuous inf

"... We discuss the Ashtekar formalism from the point of view of twelve dimensions. We first focus on the 2 + 10 spacetime signature and then we consider the transition 2 + 10 → (2 + 2) + (0 + 8). We argue that both sectors 2 + 2 and 0 + 8, which are exceptional signatures, can be analyzed from the point ..."

Abstract. We define an epistemic logic for labelled transition systems by introducing equivalence relations for the agents on the states of the labelled transition system. The idea is that agents observe the dynamics of the system modulo their ability to distinguish states and in the process learn about the current state and past history of the execution. This is in the spirit of dynamic epistemic logic but is a direct combination of HennessyMilner logic and epistemic logic. We give an axiomatization for the logic and prove a completeness theorem with respect to the class of models obtained by unfolding labelled transition systems. 1
