You can add the Assumptions globally using SetOptions[Integrate, Assumptions -> Re[k] > 0] and then use typeset notation. Alternatively, in 5.0, you can use Assuming: Assuming[Re[k] > 0, typeset integral] Cheers, Paul -- Paul Abbott Phone: +61 8 9380 2734 School of Physics, M013 Fax: +61 8 9380 1014 The University of Western Australia (CRICOS Provider No 00126G) 35 Stirling Highway Crawley WA 6009 mailto:paul at physics.uwa.edu.au AUSTRALIA http://physics.uwa.edu.au/~paul
