On the existence of sulutions of the equationLxNxand a coincidence degree theory [PDF]

open access: yesJournal of the Australian Mathematical Society, 1979
The coincidence degree for the pair (L, N) developed by Mawhin (1972) provides a method for proving the existence of solutions of the equationLx = NxwhereL: domL⊂X→Zis a linear Fredholm mapping of index zero andis a (possiblv nonlinear) mapping and Ω is a bounded open subset ofX, XandZbeing normed linear spaces over the reals.

A generalized coincidence point index [PDF]

open access: yesApplied General Topology, 2005
The paper is devoted to build for some pairs of continuous single-valued maps a coincidence point index. The class of pairs (f, g) satisfies the condition that f induces an epimorphism of the Cech homology groups with compact supports and coefficients in

Coincidence degree methods in almost periodic differential equations [PDF]

open access: yesTopological Methods in Nonlinear Analysis, 2017
The paper provides conditions for the existence of almost periodic solutions to differential equations using coincidence degree theory. A new equivalent spectral condition ensuring the compactness of integral operators on almost periodic function spaces has been established.

Existence of solutions by coincidence degree theory for Hadamard fractionaldifferential equations at resonance [PDF]

open access: yesTurkish Journal of Mathematics
Using the coincidence degree theory of Mawhin and constructing appropriate operators, we investigate the existence of solutions to Hadamard fractional differential equations (FRDEs) at resonance { − (HDγu ) (t) = f(t, u(t)), t ∈ (1, e), u(1) = 0, u(e) = ∫ e 1 u(t)dA(t), where 1 < γ < 2, f : [1, e]×R2 → R satisfies Carathéodory conditions, ∫ e 1 u(

Influence of System Parameters on Nonlinear Dynamic Characteristics of the Herringbone Gear Transmission Under Different Coincidence Degrees [PDF]

open access: yesJixie chuandong
The coincidence degree is an important parameter to reflect the number of meshing teeth of gear pairs at the same time. The appropriate coincidence degree of reasonable selection can improve transmission bearing capacity and ensure transmission stability,

On existence of periodic solutions of the Rayleigh equation of retarded type

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
In this paper, we give two sufficient conditions on the existence of periodic solutions of the non-autonomous Rayleigh equation of retarded type by using the coincidence degree theory.

Existence of solutions for fractional differential equations with three-point boundary conditions at resonance in $\mathbb{R}^n$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, by applying the coincidence degree theory which was first introduced by Mawhin, we obtain an existence result for the fractional three-point boundary value problems in $\mathbb{R}^n$, where the dimension of the kernel of fractional ...

Psychosomatics and mentalization

open access: yesEuropean Psychiatry, 2023
Introduction We have investigated the relationship between the Psychosomatic Classification method (Marty) and the Rorschach Test, with respect to the diagnosis of psychosomatic disorders, within the framework of the degree of mentalization measured by ...
