✦ Synopsis

The correlation function of two Walsh functions appears in image processing, signal multiplexing, detection and spectral analysis using Walsh functions. Though Walsh functions are two-valued, their correlation functions are real-valued and rather diffccult to evaluate. A recursive formula is developed in this paper to evaluate thx correlation functions. Some other properties of the correlation function are also discussed.

## Abstract We consider the following generalization of the notion of a structure recursive relative to a set __X.__ A relational structure __A__ is said to be a Γ(__X__)‐structure if for each relation symbol __R__, the interpretation of __R__ in __A__ is ∑ relative to __X__, where β = Γ(__R__).

We present new Jacobi-Pad6 formulae which describe the thermodynamic properties of the electron fluid throughout the full range of degeneracy. These expressions are based on the inclusion of the classical Debye-Hiickel term, the quantum virial series and ground state Monte Carlo results. Comparisons
