AbstractI will review four-dimensional gravity in the coframe-and-connection formulation (a.k.a. Palatini–Cartan formalism) and what it entails on boundaries (e.g., on Cauchy surfaces) and on corners (e.g., surfaces at infinity or surfaces around singularities in space). This full analysis will require the BV, the BFV and related formalisms and their interplay.About the speakerAlberto Cattaneo...
AbstractThe subject of analogue (or simulated) gravity has become a large area with the number of papers being of the order of a thousand. I will discuss a few types of analogues focussing on the relation between the actual gravitational field and and a fluid simulation of the field. In a sense this is directly related to specific coordinate systems for the gravitational field.Concrete simulati...
