Extends PIE representation inductively to multivariate PDEs via domain intersections, proves consistency condition for operator inverse, and enables SDP-based stability analysis with PIETOOLS software.
As such, a right-inverse to ∂ d x ∂ d y : D1 ∩ D2 → Ln 2[[0,1]2] exists only if the operators T1 and T2 commute
