PlanetPhysics/Parametric Operator

A parametric operator $$\Omega$$ with parameter $$\alpha$$ in the parametric set  $$\mathcal{A}$$ is an indexed family of operators $$(\Omega_{\alpha})_{\mathcal{A}} = \{ \Omega_{\alpha} : \alpha \in \mathcal{A} \}$$ with index $$\alpha$$ in the index set $$\mathcal{A}$$.
