Counting models in universal Horn classes
Define n
K (λ) to be either ω, or the number of non-isomorphic models inK having cardinality α, whichever cardinal is larger. This paper contains a... -
Esca** from intermediate expression swell: a continuing saga
The notion of a closed continuation is introduced, and a functional dialect of LISP is presented, using function call and return based on this... -
Existentially complete lattice-ordered groups
We investigate existentially complete lattice-ordered groups in this paper. In particular, we list some of their algebraic properties and show that...

Cryptology: The Mathematics of Secure Communication
If the model developed here for the abstract encryption/decryption channel is as general as is claimed, the discovery of asymmetric encryption...

Spacetimes
We focus attention on Lorentzian manifolds in this chapter. After a brief mathematical review, the fundamental notions of causality and time... -
Differentiation
We have really been talking about differentiation in the last two chapters, and the present one contains no really new ideas. It merely introduces a... -
Stronger than uniform convergence of multistep difference methods
This paper is concerned with the numerical integration of ordinary differential equations of the order x . Sufficient conditions and also necessary...

On Formalization
The most striking results of formalization occur in logic and mathematics.
