Syntax for Free: Representing Syntax with Binding Using Parametricity
We show that, in a parametric model of polymorphism, the type ∀α.((α → α) → α) → (α → α → α) → α is isomorphic to closed n terms. That is, the type of closed ...

What You Must Remember When Processing Data Words
We provide a Myhill-Nerode-like theorem that characterizes the class of data languages recognized by deterministic finite-memory automata (DMA). As a byproduct of this characteriza...

A Theorem Prover for Prioritized Circumscription
In a recent paper, Ginsberg shows how a backward-chaining ATMS can be used to construct a theorem prover for circumscription. Here, this work is extended to handle prioritized cir...

Graph connectivity, partial words, and a theorem of Fine and Wilf
The problem of computing periods in words, or finite sequences of symbols from a finite alphabet, has important applications in several areas including data compression, string se...

A Differential Code for Shape Representation in Image Database Applications
A new method termed the vertex representation is presented for approximating the shapes of objects of arbitrary dimensionality d (e.g., 20, 30, etc.) with orthogonal (d - 1)-dimen...
