I am being asked to define several of my algorithms in mathematical terms to describe my work to a customer. I am trying to determine if anybody knows whether common operators for collections like sequences, lists, tuples, etc have been defined. If so, is there a good reference that I could be pointed to. Thanks. I am interested in the actual symbols used. I am wondering if the following would make sense or be appropiate to anybody.
Given two sequences (or strings):
S = (A, B, C) and T = (A, D, H)
In my mind, the intersection of these sequences would look like S ∩ T = (A) and the union of these sequences would be S ∪ T = (A, B, C, A, D, H)
