    You will get better answers if you can tell us a bit more. Where did you come across the term? What parts of the discussion there made sense to you and what parts left you confused? You'll get a bunch of hits if you google for "hypercylindrical line element" - do they help, and if not, what more specific questions do they leave you with?

    I am trying to describe sound wave propagation in the real projective space RP3. This procedure has been done for sound wave propagation on a background in a medium with the background topology of RP2 - using a line element with cylindrical coordinates. The FULL cylindrical line element is easily found.. and as shown below in the spacetime metric of an anisotropic uniaxial system in three-dimensions.

    I am looking for the FULL hyper-cylindrical line element --- and am having a lot of trouble finding it! just looking to see if anyone knows of it.
