    [itex]\oplus[/itex] what does this symbol mean. I was confused in special relativity when notes say u' [itex]\oplus[/itex] v [itex]\neq[/itex] u' + v.

    Hi Lizwi! :smile:
    What is the context?

    Sometimes mathematicians run out of symbols, and recycle a symbol they think nobody wants! :biggrin:

    My guess is that this is the addition of relative-velocities formula, and that this author is simply using it as a shorthand for that form of addition.

    (in other words: it's his symbol for multiplication in the group of relative-velocities)
