Marco van den Beld-Serrano
Given a fixed past-directed timelike vector field, does there exist a time function whose gradient is optimally aligned with it? We address this question by introducing a functiona…

Baryogenesis in Conformally Flat Spacetimes
Felix Finster, Marco van den Beld-Serrano
Based on a baryogenesis mechanism originating from the theory of causal fermion systems, we analyze its main geometric and analytic features in conformally flat spacetimes. An expl…

Baryogenesis in Minkowski Spacetime
Felix Finster, Marco van den Beld-Serrano
Based on a mechanism originally suggested for causal fermion systems, the present paper paves the way for a rigorous treatment of baryogenesis in the language of differential geome…
