comment Continuous Function + open set
When you say: "$T(x) \in S_0" is "T^{-1}(x) \in S_0$"?

Why the inverse image preserver set inclusion?

Which is the guarantee that such for all $\epsilon$ the $\delta$-neighborhood belong $S_0$?

comment Properties matrix $A^2=I$
ok, and this question -- How I will be able to represent $A := \sum_{1\le k\le n}\lambda_k P_k$ What's are the $P_k$? where $\lambda k$ are the eigenvalues and $P_k$ are projections

then only $I$ and $-I$ satisfy $A^2=I$?

@anon thank by your replys, the vector space is $\mathbb{C}^4$ and the unitary operator $U_1\otimes U_2 \in \mathbb{C}^{4\times 4}$

mmm, then I will be able to say: Any vector $|\psi\rangle$ belong to set with the form $V\otimes W$?

not, because if this happens then $|\psi\rangle$ is factorizable
