This paper establishes some hidden connections between the theory of generalized algebraic multiplicities, $\chi$, and the notion of orientability of vector bundles. The novel approach adopted in it facilitates the definition of several invariants cl

In this paper, we prove a finite dimensional approximation scheme for the Wiener measure on closed Riemannian manifolds, establishing a generalization for $L^{1}$-functionals, of the approach followed by Andersson and Driver on [1]. We follow a new a

We deal with a planar differential system of the form \begin{equation*} \begin{cases} \, u' = h(t,v), \\ \, v' = - \lambda a(t) g(u), \end{cases} \end{equation*} where $h$ is $T$-periodic in the first variable and strictly increasing in the second va

This paper reveals some new analytical and geometrical properties of the generalized algebraic multiplicity, χ, introduced in [7] , [5] and further developed in [15] , [17] , [18] . In particular, it establishes a completely new connection between

In this paper, we prove an analogue of the uniqueness theorems of Führer [15] and Amann and Weiss [1] to cover the degree of Fredholm operators of index zero constructed by Fitzpatrick, Pejsachowicz and Rabier [13], whose range of applicability is s

This paper introduces a new constant $$\kappa $$ , with a definition closely related to that of the Euler–Mascheroni’s constant $$\gamma $$ . Some integrals and infinite sums are evaluated in terms of $$\kappa $$ .

In this article we prove some identities which allow us to evaluate some multiple unit square integrals. In our examples we will give the value of some double and triple integrals. Then, we prove several classical integral formulas with the help of t
