Classification by Estimating the Cumulative Distribution Function for Small Data

IEEE Access, 2023
In this paper, we study the classification problem by estimating the conditional probability function of the given data. Different from the traditional expected risk estimation theory on empirical data, we calculate the probability via Fredholm equation,

Static Stretching Acutely Reduces the Ergogenic Effects of Caffeine on Sprint Performance but Not Maximal Ball Velocity in Football Players

European Journal of Sport Science, Volume 26, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the independent and combined effects of caffeine and static stretching (SS) on maximal ball velocity and 30‐m sprint performance. Sixteen male amateur football players performed 30‐m sprint and an instep kicking ball velocity test under six conditions.

Existence of Solutions of Nonlinear Stochastic Volterra Fredholm Integral Equations of Mixed Type

International Journal of Mathematics and Mathematical Sciences, 2010
We establish sufficient conditions for the existence and uniqueness of random solutions of nonlinear Volterra-Fredholm stochastic integral equations of mixed type by using admissibility theory and fixed point theorems.

Large‐Amplitude Periodic Solutions to the Steady Euler Equations With Piecewise Constant Vorticity

Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.
ABSTRACT We consider steady solutions to the incompressible Euler equations in a two‐dimensional channel with rigid walls. The flow consists of two periodic layers of constant vorticity separated by an unknown interface. Using global bifurcation theory, we rigorously construct curves of solutions that terminate either with stagnation on the interface ...

Orientability of Fredholm families and topological degree [PDF]

, 1994
We construct a degree theory for oriented Fredholm mappings of index zero between open subsets of Banach spaces and between Banach manifolds. Our approach is based on the orientation of Fredholm mappings: it does not use Fredholm structures on the domain

Integral operators with the generalized sine-kernel on the real axis

, 2010
The asymptotic properties of integral operators with the generalized sine kernel acting on the real axis are studied. The formulas for the resolvent and the Fredholm determinant are obtained in the large x limit. Some applications of the results obtained

Adenosine and acute low oxygen conditions suppress urinary bladder contractility through the activation of adenosine 2B receptors and large‐conductance calcium‐activated potassium channels

The Journal of Physiology, Volume 604, Issue 1, Page 379-394, 1 January 2026.
Abstract figure legend Detrusor smooth muscle surrounding the urinary bladder produces transient pressure events essential for sensing bladder fullness during the filling phase. We investigated the role of adenosine, a ubiquitous signalling molecule, in regulating bladder smooth muscle function.

A Fredholm alternative for quasilinear elliptic equations with right-hand side measure

Advances in Nonlinear Analysis, 2016
We consider a quasilinear elliptic equation with right-hand side measure, which does not satisfy the usual coercivity assumption. We prove an existence result in the line of the Fredholm alternative. For this purpose we develop a variant of degree theory

Sc-Smoothness, Retractions and New Models for Smooth Spaces

, 2010
We survey a (nonlinear) Fredholm theory for a new class of ambient spaces called polyfolds, and develop the analytical foundations for some of the applications of the theory.

Chaos, External Noise and Fredholm Theory [PDF]

Progress of Theoretical Physics, 1980
Summary: The Fredholm theory of integral equations is applied to the Perron-Frobenius equation which determines the invariant measure of nonlinear difference equations. The resultant Fredholm determinant \(D\) is identical to \(1/\zeta\). where \(\zeta\) is the Artin-Mazur-Ruelle \(\zeta\)-function. From the investigation of \(D\) we get the observable
