Can a set be symmetric and antisymmetric
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) . Bosons and femions. Physical solutions must be eigenfunctions of ˆP12 (i.e., ˆH and ^ P12 commute). WebLet P = P (A) be the power set of A. Let R be the relation on P defined by: For all X, Y ∈ P, XR Y if and only if ∣ X ∪ Y ∣ ≤ ∣ X ∪ {1, 2} ∣. (a) Is R reflexive? symmetric? antisymmetric? transitive? Prove your answers. (b) How many S ∈ P are there so that {3} RS? Explain. (c) How many S ∈ P are there so that SR {3}

WebAnswer (1 of 2): Let’s take a relation R on set A = \{x,y\} Then, Reflexive Relations : (x,x)\in R \forall x\in A Asymmetric Relations : \exists(x,y)\in R \implies (y,x)\notin R \forall x,y\in A Now if R is Reflexive then (x,x) and (y,y) are definitely it’s elements. But from the definition... WebJul 7, 2024 · To prove an equivalence relation, you must show reflexivity, symmetry, and transitivity, so using our example above, we can say: Advertisement. Reflexivity: Since a – a = 0 and 0 is an integer, this shows that (a, a) is in the relation; thus, proving R is reflexive. Symmetry: If a – b is an integer, then b – a is also an integer.
