WebApr 5, 2015 · Also, I'm curious to know since relations can both be neither symmetric and anti-symmetric, would R = {(1,2),(2,1),(2,3)} be an example of such a relation? Yes. Symmetric or antisymmetric are special cases, most relations are neither (although a lot of useful/interesting relations are one or the other). WebJan 31, 2024 · A relation can be both symmetric and antisymmetric (e.g., the equality relation), and there are relations which are neither symmetric nor antisymmetric (e.g., the “preys on” relation on biological species).

WebMar 18, 2024 · For a meaningful solution we must have a wavefunction which has a probability amplitude unchanged by ˆP12: it must be either symmetric or antisymmetric with respect to exchange: ˆP12 ψ(r1, r2) = ± ψ(r2, r1) .
