Delta One

In financial derivatives, where the hedge position corresponds one-for-one with the notional of the derivative.

This is always true of forwards and swaps: thus, Jérôme Kerviel, as a swaps trader, was on SocGen's Delta One desk.

The amount of money that Kerviel was making, as a Delta One trader with a 500K risk limit, was suspicious.

One

A multiplicative identity of a semiring. For a semiring R, 1 is defined as an element so that for every a being an element of R:
1⊗a = a⊗1 = a

Min-tropical semiring is a semiring (ℝ ∪ {+∞}, ⊕, ⊗) with ⊕ defined as min, and ⊗ defined as the addition of two numbers. By that definition, zero is +∞, and one is 0

NO ONE CARES

STFU, no one cares what your name means.

Everyone posted their definition online but no one cares.

One Direction

Finally, a pop band that uses instruments.

Virgin: I like One Direction
Chad: Tbh, they’re not too bad.
Virgin: I don’t like John Mayer.
Chad: And there we go. Have a sad little life.

No one is no one, only one

Something that blurted out of my mouth when I was pacing around my room, talking to myself about love, suffering from wanting-to-be-held syndrome, AND HAD ONLY 4 HOURS OF SLEEP THE LAST NIGHT.

I think it was supposed to mean, “Everyone has an only one” or something.

“No one is no one, only one. Words from a young, hormone-crazy lady.”
