The equivariant perturbation theory concerns perturbation functions in Gomory–Johnson's infinite group problem, including functions that need not be piecewise linear. Breakdown con…

Let $f\in(0,1)$ be fixed, and consider the infinite group problem with variables $s_r\in\mathbb{Z}_+$ for $r\in[0,1)$, finite support, and the equality constraint … where additions…

Let $\pi$ be a minimal valid function for $R_f(\mathbb R^2,\mathbb Z^2)$ that is piecewise linear and continuous on $\mathcal P_q$. The function $\pi$ is diagonally constrained if,…
