Abstract

We present a reconstruction algorithm for cosmological models based on $f(\mathcal{Q})$ gravity. We specifically focus on Bianchi type I and Friedmann-Lema\^{\i}tre-Robertson-Walker spacetimes, obtaining exact solutions that might have application in a variety of scenarios such as spontaneous isotropization of Bianchi type I models, dark energy, and inflation, as well as pre-big bang cosmologies.
