Four lectures on Euler integrals

open access: yesSciPost Physics Lecture Notes, 2023
These lecture notes provide a self-contained introduction to Euler integrals, which are frequently encountered in applications. In particle physics, they arise as Feynman integrals or string amplitudes.

Information geometry of Markov Kernels: a survey

open access: yesFrontiers in Physics, 2023
Information geometry and Markov chains are two powerful tools used in modern fields such as finance, physics, computer science, and epidemiology. In this survey, we explore their intersection, focusing on the theoretical framework.

On 4-dimensional Einsteinian manifolds with parallel null distribution [PDF]

open access: yesریاضی و جامعه, 2023
In this paper, we investigate the Einsteinian manifolds with parallel null distribution. For this purpose, we first obtain the equations, which are known as Einstein's equations, that lead to finding the mentioned manifolds and then, we reduce Einstein's

Geometry optimization of a muon-electron scattering detector

open access: yesPhysics Open, 2020
A high-statistics determination of the differential cross section of elastic muon-electron scattering as a function of the transferred four-momentum squared, dσel(μe→μe)/dq2, has been argued to provide an effective constraint to the hadronic contribution

Integrating Pedagogical Approaches in the Study of Conic Sections Using Differential Equation and Analysis via Bayesian Inference

open access: yesEngineering Proceedings, 2023
In science and technology, the application of mathematics and mathematical modelling is crucial. A more conceptual and axiomatic approach has been taken in developing the narrative from geometry in the enormous history of mathematics.

Geometry aware physics informed neural network surrogate for solving Navier–Stokes equation (GAPINN)

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
Many real world problems involve fluid flow phenomena, typically be described by the Navier–Stokes equations. The Navier–Stokes equations are partial differential equations (PDEs) with highly nonlinear properties. Currently mostly used methods solve this

Quantum geometric tensors from sub-bundle geometry [PDF]

open access: yesQuantum
The geometric properties of quantum states are crucial for understanding many physical phenomena in quantum mechanics, condensed matter physics, and optics. The central object describing these properties is the quantum geometric tensor, which unifies the

Magnetic Curves in Differential Geometry: A Comprehensive Survey

open access: yesMathematics
The concept of “magnetic lines of force,” or “magnetic curves”, was introduced in the 1830s by Michael Faraday (1791–1867); his work provided the foundation for the modern understanding of magnetic fields.
