On Solutions of a Nonlinear Erdélyi-Kober Integral Equation
We conduct some investigations concerning the solvability of a nonlinear integral equation of Erdélyi-Kober type. To facilitate our study we will first consider a nonlinear integral equation of Volterra-Stieltjes type.

Path Integral for Quantum Operations
In this paper we consider a phase space path integral for general time-dependent quantum operations, not necessarily unitary. We obtain the path integral for a completely positive quantum operation satisfied Lindblad equation (quantum Markovian master ...

Improved-Accuracy Source Reconstructionon Arbitrary 3-D Surfaces [PDF]
This paper presents a novel formulation of the source reconstruction problem on arbitrary three-dimensional (3-D) surfaces based on integral equations. Rigorous boundary integral field identities are employed to enforce that the two unknown currents are ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

On a class of integral equations [PDF]
where g and h are given and f is unknown. The number a may be finite or infinite. The first integral is taken in the sense of a Cauchy principal value. For h(x, t) 8O, this reduces to a well known integral equation of airfoil theory and has been treated extensively, mainly by Fourier methods, cf. [2 ]. E. Reissner [3 ] has applied this method to (1) in

Prescribing integral curvature equation [PDF]
In this paper we formulate new curvature functions on $\mathbb{S}^n$ via integral operators. For certain even orders, these curvature functions are equivalent to the classic curvature functions defined via differential operators, but not for all even ...

Network topology drives population temporal variability in experimental habitat networks
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Convergence of Numerical Solution of Generalized Theodorsen’s Nonlinear Integral Equation
We consider a nonlinear integral equation which can be interpreted as a generalization of Theodorsen’s nonlinear integral equation. This equation arises in computing the conformal mapping between simply connected regions.

On global attractivity of solutions of a functional-integral equation
We prove an existence theorem for a quadratic functional-integral equation of mixed type. The functional-integral equation studied below contains as special cases numerous integral equations encountered in nonlinear analysis.
