Goals in a Formal Theory of Commonsense Psychology
In the context of developing formal theories of commonsense psychology, or how peole think they think, we have developed a formal theory of goals. In it we explicate and axiomatiz...

Separation of Concerns in the Formal Design of Real-Time Shared Data-Space Systems
This paper proposes a formal framework for the design of real-time shared data-space systems. The proposed method separates the concerns of functionality, behavior, and timing. Th...

A formal study of information retrieval heuristics
Empirical studies of information retrieval methods show that good retrieval performance is closely related to the use of various retrieval heuristics, such as TF-IDF weighting. On...

Analytic Solutions of Linear Difference Equations, Formal Series, and Bottom Summation
We consider summation of consecutive values (v), (v +1), . . . , (w) of a meromorphic function (z) where v, w ZZ. We assume that (z) satisfies a linear difference equation L(y) = ...

From formal numerical solutions of elliptic PDE's to the true ones
Abstract. We propose a discretization scheme for a numerical solution of elliptic PDE's, based on local representation of functions, by their Taylor polynomials (jets). This s...
