Abstract. In this note we report the following computational results on partial spread functions in 8 variables: (i) the numbers of equivalence classes of partial spread functions ...
By the relationship between the Walsh spectra at partial points and the Walsh spectra of its sub-functions, by the action of general linear group on the set of Boolean functions, ...

We recall the notions of weak and strong Euler characteristics on a first order structure and make explicit the notion of a Grothendieck ring of a structure. We define partially or...
