On the Existence of Equilibrium Points,

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

THE MOMENTS OF THE AREA UNDER REFLECTED

This paper develops a recursion formula for the conditional moments of the area under the absolute value of Brownian bridge given the local time at 0.. The method of power series

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

of Quillen on the vanishing of cotangent homology

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

On the Invariant Theory of the B´ ezoutiant

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)

The uncountable spectra of countable theories

The main technical result of the paper is the proof of Theorem 3.3, which asserts that the embeddability of certain countable configurations of elements into some model of the

For X-valued vector functions the Dinculeanu integral with respect to a σ-additive scalar measure on P (see Note 1) is the same as the Bochner integral and hence the Dinculeanu
