Spritz: General relativistic magnetohydrodynamics with neutrinos
2020
We here present a new version of the publicly available general relativistic magnetohydrodynamic (GRMHD) code $\texttt{Spritz}$, which now includes an approximate neutrino leakage scheme able to handle neutrino cooling and heating. The leakage scheme is based on the publicly available $\texttt{ZelmaniLeak}$ code, with a few modifications in order to properly work with $\texttt{Spritz}$. We discuss the involved equations, physical assumptions, and implemented numerical methods, along with a large battery of general relativistic tests performed with and without magnetic fields. Our tests demonstrate the correct implementation of the neutrino leakage scheme, paving the way for further improvem…
Kant and Baumgarten on positing. Kant's notion of positing as a response to that of Baumgarten
2020
In the literature on Kant’s philosophy, it is almost universally ignored that Baumgarten used the notion of positing in a technical sense before Kant. In this article, I try to fill this gap in the literature by providing an analysis of Kant’s notion of positing in relation to Baumgarten’s one. I first show how Kant's differentiation of relative and absolute positing is not simply an alternative to Baumgarten's notion of existence, but is instead an alternative to his (usually ignored) notion of positing; I then develop a positive account of Kant’s notion of positing.
