It would be a shame if the complex conjugate operation did not make it into MathML. Although it may be getting close to the boundary of the level of mathematics that MathML wants to represent, I think it is still within the level. It is certainly no more sophisticated than partial derivatives. One usage that immediately comes to mind is in quantum mechanics where the probability function is defined as: <math> <declare type="fn"> <ci>P</ci> <apply> <times/> <apply> <conj/> <ci>Ψ</ci> <apply> <ci>Ψ</ci> </apply> </declare> </math> -- Russell O'Connor roconnor@uwaterloo.ca <URL:http://www.undergrad.math.uwaterloo.ca/%7Eroconnor/> "And truth irreversibly destroys the meaning of its own message" -- Anindita Dutta, "The Paradox of Truth, the Truth of Entropy"Received on Friday, 13 March 1998 22:37:15 UTC
