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

Then it follows immediately from a suitable version of “Hensel’s Lemma” [cf., e.g., the argument of [4], Lemma 2.1] that S may be obtained, as the notation suggests, as the m A

Classical definitions of locally complete intersection (l.c.i.) homomor- phisms of commutative rings are limited to maps that are essentially of finite type, or flat.. The

We study the classical invariant theory of the B´ ezoutiant R(A, B) of a pair of binary forms A, B.. We also describe a ‘generic reduc- tion formula’ which recovers B from R(A, B)

After performing a computer search we find that the density of happy numbers in the interval [10 403 , 10 404 − 1] is at least .185773; thus, there exists a 404-strict

The aim of this paper is to prove existence, uniqueness, and continu- ous dependence upon the data of solutions to mixed problems for pluri- parabolic equations with nonlocal
