I don't really know why I know how to get from $$\theta(\Omega, 0)$$ to $$\theta(\Omega, 1)$$ but now from $$\theta(\omega, 0)$$ to $$\theta(\omega, 1)$$. I actually thought about both of them but I ended up sleeping. Then, I tried to use $$\varphi$$ instead and it still failed (why did I even do that). Anyway, the reason don't know how to get from $$\theta(\omega, 0)$$ to $$\theta(\omega, 1)$$ is that I don't know the fundamental sequence for $$\varphi(\omega, 1)$$.
