Ah, OK! Thank you anyway! |

Tangent vectors on the algebra of trigonometric polynomials
Peter, I am not sure I understood. Are you saying that the problem appears only for non-compact $G$, or for all $G$? |

Mariano, I have made the corrections, now ${\sf Trig}(G)$ is defined. |

A textbook on linear algebra where involutions on linear spaces are considered
Mariano, maybe you are right. Perhaps, it will be reasonable to do what you suggest... |

Excuse me, the numbers I, 14.1 in the reference to Borel, what do they mean? I can't find... |

This will be my handbook. Like Bible. :) |

It is easy to prove of course, but it is not good to write this proof in a paper, or to use this result without reference. Ben, I don't like the formulation of this fact that Fulton and Harris give at p.444. This is not for normal mathematician, you must have some background in representation theory to recognize what I need in what they say. I believe there are texts with simpler formulations. And, by the way, I need also the constructions of real and imaginary parts, and their properties. Of course this is trivial, but I'd like to have a book on my table. |

"a complex vector space is the complexification of a real vector space just when it bears a conjugate linear involution operator" -- I need this and the construction of involution on the dual space. But I think it's not nice to write this without reference. Or you mean that this is stated in the Fulton-Harris book? |

No doubts, but which book to cite? |

I think this is not what I need. They introduce the operation of taking complex conjugate vector, but only in the case when $X$ is a complexification of a given real vector space $Y$, not for an arbitrary complex vector space $X$... Or I missed something? |
