Quadratic Spline Collocation for Volterra Integral Equation

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2004
In the traditional step-by-step collocation method with quadratic splines for Volterra integral equations an initial condition is replaced by a not-a-knot boundary condition at the other end of the interval. Such a nonlocal method gives the uniform boundedness of collocation projections for all parameters c in (0,1) characterizing the position of ...

Monotonic solutions of functional integral and differential equations of fractional order

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
The existence of positive monotonic solutions, in the class of continuous functions, for some nonlinear quadratic integral equations have been studied by J. Banas. Here we are concerned with a singular quadratic functional integral equations.

Existence Theorems for Some Quadratic Integral Equations

open access: yesJournal of Mathematical Analysis and Applications, 1998
The considered quadratic integral equations arise in the theories of radiative transfer and neutron transport and in the kinetic theory of gases. The theory of measures of noncompactness is used to prove few existence theorems for some quadratic integral equations. The theory is illustrated by two examples.

Solvability of functional quadratic integral equations with perturbation [PDF]

open access: yesOpuscula Mathematica, 2013
We study the existence of solutions of the functional quadratic integral equation with a perturbation term in the space of Lebesgue integrable functions on an unbounded interval by using the Krasnoselskii fixed point theory and the measure of weak ...

Numerical Solution of a Quadratic Integral Equation through Classical Schauder Fixed Point Theorem

open access: yesCommunications in Advanced Mathematical Sciences, 2021
In this paper, we investigate the existence of at least one solution on the closed interval for quadratic integral equations with non-linear modification of the argument in Hölder spaces using the technique in the classical Schauder fixed point theorem.

ON SOLVABILITY OF QUADRATIC HAMMERSTEIN INTEGRAL EQUATIONS IN HÖLDER SPACES

open access: yesMatematički Vesnik, 2022
Summary: Using Schauder's fixed point theorem we consider the solvability of a quadratic Hammerstein integral equation in the space of functions satisfying a Hölder condition. An example is included to illustrate our results.

Closed-Loop Solvability of Stochastic Linear-Quadratic Optimal Control Problems with Poisson Jumps

open access: yesMathematics, 2022
The stochastic linear–quadratic optimal control problem with Poisson jumps is addressed in this paper. The coefficients in the state equation and the weighting matrices in the cost functional are all deterministic but are allowed to be indefinite.
