Analysis of nonlinear oscillators using volterra series in the frequency domain Part I : convergence limits [PDF]
, 2009 The Volterra series representation is a direct generalisation of the linear convolution integral and has been widely applied in the analysis and design of nonlinear systems, both in the time and the frequency domain.

Measure‐valued processes for energy markets
Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Solving one pseudo-Volterra integral equation
Қарағанды университетінің хабаршысы. Математика сериясы, 2019 In this paper, we study the solvability of a second - kind pseudo-Volterra integral equation. By replacing the right - hand side and the unknown function, the integral equation is reduced to an integral equation, the kernel of which is not «compressible»

On a nonlinear Volterra integral equation
Journal of Differential Equations, 1973 Also note the comments. made on (1.1) in [2]. More recently Eq. (1.1) has been analyzed in [I and 31 under hypotheses related to those of Theorem I. Comparing the present result with the results of [3] we observe the following. In addition to the full hypothesis of Theorem 1 above, certain smoothness conditions were imposed on a(t) and f(i) in [3 ...

Optimal Liquidation With Signals: The General Propagator Case
Mathematical Finance, EarlyView.ABSTRACT We consider a class of optimal liquidation problems where the agent's transactions create transient price impact driven by a Volterra‐type propagator along with temporary price impact. We formulate these problems as maximization of a revenue‐risk functionals, where the agent also exploits available information on a progressively measurable ...

Integral equations of Volterra type
Journal of Mathematical Analysis and Applications, 1978 AbstractThe behavior of exact solutions to Volterra linear and non-linear integral equations with negative or positive, monotone kernels is studied. It includes properties such as the number of zeroes, boundedness and monotonicity of the solutions on the infinite interval.

Noûs, EarlyView.Abstract It is well‐recognized in the sciences that a multitude of nonequivalent models are used by researchers to fulfill a range of goals, even for the same target system, a result known broadly as model pluralism. The possibility of the same form of pluralism occurring in logic, however, has not been adequately considered.

A successive iterative approach for two dimensional nonlinear Volterra-Fredholm integral equations [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2014 In this paper, an iterative scheme for extracting approximate solutions of two dimensional Volterra-Fredholm integral equations is proposed. Considering some conditions on the kernel of the integral equation obtained by discretization of the integral ...

Astroglial CB1 Reveal Sex‐Specific Synaptic Effects of Amphetamine
Glia, Volume 73, Issue 8, Page 1673-1691, August 2025.Main Points Astroglial CB1 mediate long‐term depression in the NAc through purine release. Amphetamine occludes LTD in male mice by inducing the saturation of A1 receptors. Astroglial CB1 mediate behavioral amphetamine effects in males, but not in females.
