Let $\eta$ be a profile, let $\mathrm{v}$ be a four-velocity, let $C\in\{F^{\mu\nu},j^\mu\}$ be an observable field, and let $\Psi,\Psi'\in\mathcal{D}_2$. The BRST charge is denote…

Let $\boldsymbol{\eta}$ be a profile, let $C\in\mathcal{F}$ be a polynomial in fields and their derivatives, and let $\Psi,\Psi'\in\mathcal{D}_2$. A renormalization scheme for time…
