@DavidRoberts: I think you're reading something into the question. It looks to me like the OP is just being cautious ... |

Norm of a matrix operator with a special structure
@Suvrit: it is hard to read "tone" from printed text ... it always surprises me when people can't tell I'm being sarcastic, for example |

Norm of a matrix operator with a special structure
@Suvrit: it's not positive because it's not self-adjoint. |

Is $\mathcal{P}(\omega)/fin$ with the interval topology path-connected?
Oh, I misread the definition, sorry. |

According to your definition of "interval topology", it looks as though every subbasic open set is also closed, in any poset ... |

Huh. No, I haven't encountered this. But no doubt negativity towards other fields is fairly common --- I can be guilty of this myself --- though I suppose I feel it's something one shouldn't take too seriously. That's just human nature. |

What are the applications of operator algebras to other areas?
@PaulSiegel: partly ... I just looked up the citation and it includes "applications of the theory of C*-algebras to foliations and differential geometry in general". A version of his index theorem appears in his paper "A survey of foliations and operator algebras" which is based on a talk given in 1980. |

@Vincent: Probably the part about "I've heard some things about the reputation of this area" and the placement of "operator algebras" in quotes gave this question a very different tone. I will edit the question to give it a more neutral tone. |
