Δ definition

Δ normally means symmetric difference. For typographic convenience, “ Δ” will be used in Part II for symmetric difference in the sense of ∈2; “ δ” will mean symmetric difference in the sense of ∈0. I.e., xδ y =df {z ∣ z ∈0 x ≢ z ∈0 y}0, and x Δy =df {z ∣ z ∈2 x ≢ z ∈2 y}2. (“ 𝛛 ”, defined in a later section, will also be distinct.)
