Checks on QED and strong-isospin breaking corrections to $a_{\mu }^{\mathrm{H}\mathrm{V}\mathrm{P}}$

At the current levels of precision reached in the measurement of the muon g-2 by Fermilab, it is essential to control QED and strong isospin breaking corrections to the HVP contribution to the muon g-2. Here we present a number of cross-checks performed on the results for those corrections presented in the BMW’s collaboration 2020 computation.
