Does the U in AUB mean union, ∪, A∪B ? Does AUB mean the size of the set A∪B ? Does ||A| mean the size of the set A ?
Does the E in aEA mean the membership function, ∈ ? Like is it perhaps a double summation,
sum( a in A, sum(b in B, d(a,b) ) )
which is to say the sum of d over all pair-wise combinations of the elements of A and B ?

What does it mean to take the derivative of a value with respect to another value? The derivative of 7 with respect to 19 is not defined.
If they were sets of variable names then it could potentially make sense.
