We study computer virology from an abstract point of view. Viruses and worms are self-replicating programs, whose constructions are essentially based on Kleene's second recurs...
The n-ary first and second recursion theorems formalize two distinct, yet similar, notions of self-reference. Roughly, the n-ary first recursion theorem says that, for any n algo...
Abstract. Intuitively, a recursion theorem asserts the existence of selfreferential programs. Two well-known recursion theorems are Kleene’s Recursion Theorem (krt) and Rogers’...
