On the Definition of Energy Flux in One-Dimensional Chains of Particles
We review two well-known definitions present in the literature, which are used to define the heat or energy flux in one dimensional chains. One definition equates the energy variation per particle to a discretized flux difference, which we here show it ...

Fourier integral operators with fold singularities. [PDF]
Sharp \(L^ 2 \to L^ q_ \alpha\) estimates are proved for a class of Fourier integral operators with associated canonical relation \({\mathcal C} \subset T^*X \times T^*Y\). It is assumed that one of the projection to \({\mathcal C} \to T^*X\) or \({\mathcal C} \to T^*Y\) is a fold or a submersion with folds.

In the three-dimensional open rectangular domain, the problem of the identification of the redefinition function for a partial differential equation with Gerasimov–Caputo-type fractional operator, degeneration, and integral form condition is considered ...

Multigrid method for pricing European options under the CGMY process
We propose a fast multigrid method for solving the discrete partial integro-differential equations (PIDEs) arising from pricing European options when the underlying asset is driven by an infinite activity Lévy process.

One result on boundedness of the Hilbert transform in Marcinkiewics spaces
In mathematics and in signal theory, the Hilbert transform is an important linear operator that takes a real-valued function and produces another real-valued function.

Workflow of the parameter optimization process for ITSC fault detection, applying Differential Evolution optimization and the Smooth Pseudo Wigner‐Ville Distribution for signal processing. The optimized parameters are then used in the failure identification pipeline, which combines the signal processing with a YOLO‐based architecture for fault severity

We propose a new approach to the problem of finding the eigenvalues (energy levels) in the discrete spectrum of the one-dimensional Hamiltonian with an attractive Gaussian potential by using the well-known Birman-Schwinger technique. However, in place of

In this communication we have studied well known physical process of two-dimensional advection–diffusion phenomena. The advection–diffusion equation is time-fractionalized by exploiting Atangana-Baleanu fractional derivative operator.
