In order to find, up to isomor- phism, all (connected) edge-transitive elementary abelian regular covering projections of the Heawood graph it suffices to compute all H

The proof there does not use the fact that H ∗ (X, C[2]) has a counit, in fact it only uses its diagonal map. It relies on the earlier work in [Leh99], which has been extended to

If the S n -equivariant count of points of this space, when considered as a function of the number of elements of the finite field, gives a polynomial, then using the purity we

In this paper, we focus on the existence and some properties of disease-free and endemic equilibrium points of a SVEIRS model subject to an eventual constant regular vaccination

(We first look at how large the prime factors of t are, and then at how many there are per splitting type.) The former fact ensures that the above-mentioned bound O((log t) ) on
