The simply connected level-set conjecture for checkerboard switching
Let R∈NpR\in\mathbb{N}^pR∈Np, C∈NqC\in\mathbb{N}^qC∈Nq, and let M∈Mp,q({−1,0,1})\mathbf{M}\in\mathcal{M}_{p,q}(\{-1,0,1\})M∈Mp,q({−1,0,1}). For each integer iii, let Pi(M)\mathcal{P}_i(\mathbf{M})Pi(M) denote the set of cells at l…
