Let D be a division ring with center k, and let D-dagger be its multiplicative group. We investigate the existence of free groups in D-dagger, and free algebras and free group algebras in D. We also go through the case ...

This article reflects on approaches to community making, recounting the experience of a group of activists running two workshops in a prison in Argentina, working from a free software and free culture perspective.

This thesis aims to present Peter van Inwagen's work on the problem of free will, as expressed in An Essay on Free Will (1983). Such approach does not investigate what free will is in itself or whether agents have free ...

We prove that any two Poisson dependent elements in a free Poisson algebra and a free Poisson field of characteristic zero are algebraically dependent, thus answering positively a question from Makar-Limanov and Umirbaev ...

In this paper we study a one phase free boundary problem for the p (x)-Laplacian with non-zero right hand side. We prove that the free boundary of a weak solution is a C1,α surface in a neighborhood of every "flat" free ...
