Antisymmetric

Adjective

1. Having the property that, for any two distinct elements of S, at least one is not related to the other via R; equivalently, having the property that, for any x, y ∈ S, if both xRy and yRx then x=y.
2. Whose sign changes on the application of a matrix transpose or some generalisation thereof: Whose transpose equals its negative (i.e., M = −M); That changes sign when any two indices are interchanged (e.g., Tijk = -Tjik); For which B(w,v) = -B(v,w).
