applications of C$^*$-algebras in the field of PDEs
I disagree with the decision to close this question. I'm not aware of a large body of applications of C*-algebra to PDEs. Could any of those who voted to close suggest other examples besides mine? |

Extend product sigma-algebra to cross-constant sets
I refer to a theorem of Banach and Kuratowski. |

Extend product sigma-algebra to cross-constant sets
@Jochen: no, the axiom of choice excludes a translation-invariant measure on [0,1]. |

(Minor typo in condition 2: surely you mean $A \subseteq \Omega$.) |

Does every commutative $*$-algebra of operators on a prehilbert space have a character?
@Yurii, please post details when you're ready. Sounds interesting. |

C*-Algebras: Dynamics vs. Derivations
I guess the hint would be that exponentiating the generators should recover the one-parameter groups. The key technical point is that the generators have dense domain, which you can prove using a mollifier. |

@Christian: I don't understand, involution is entrywise complex conjugate? Does this satisfy $\langle Av,w\rangle = \langle v, A^*w\rangle$? |
