Formalization of Integral Linear Space [PDF]

open access: yesFormalized Mathematics, 2011
Summary: In this article, we formalize integral linear spaces, that is a linear space with integer coefficients. Integral linear spaces are necessary for lattice problems, LLL (Lenstra-Lenstra-Lovász) base reduction algorithm that outputs short lattice base and cryptographic systems with lattice.

Line Defects in Quasicrystals

open access: yesCrystals
The six-dimensional framework of the integral formalism for line defects (straight dislocations and line forces) in anisotropic elasticity has been extended to a 2n-dimensional integral formalism for line defects in quasicrystals (n=4,5,6 for one-, two-,

An operational calculus formulation of fractional calculus with general analytic kernels

open access: yesElectronic Research Archive, 2022
Fractional calculus with analytic kernels provides a general setting of integral and derivative operators that can be connected to Riemann–Liouville fractional calculus via convergent infinite series.

Line Defects in One-Dimensional Hexagonal Quasicrystals

open access: yesMathematics
Using the eight-dimensional framework of the integral formalism of one-dimensional quasicrystals, the analytical expressions for the displacement fields and stress functions of line defects, which are dislocations and line forces, in one-dimensional ...

Path integrals: From quantum mechanics to photonics

open access: yesAPL Photonics, 2021
The path integral formulation of quantum mechanics, i.e., the idea that the evolution of a quantum system is determined as a sum over all the possible trajectories that would take the system from the initial to its final state of its dynamical evolution,

Virtual Residue and an Integral Formalism [PDF]

open access: yesThe Journal of Geometric Analysis, 2018
We generalize Grothendieck's residues $Res\frac {s}$ to virtual cases, namely cases when the zero loci of the section $s$ has dimension larger than the expected dimension(zero). We also provide an exponential type integral formalism for the virtual residue, which can be viewed as an analogue of the Mathai-Quillen formalism for localized Euler classes.

Self dual models and mass generation in planar field theory [PDF]

open access: yes, 2001
We analyse in three space-time dimensions, the connection between abelian self dual vector doublets and their counterparts containing both an explicit mass and a topological mass.

Challenges to Path Integral Formulations of Quantum Theories

open access: yes, 2007
The functional integral has many triumphs in elucidating quantum theory. But incorporating charge fractionalization into that formalism remains a challenge.Comment: 8 pages, 5 ...

Anomaly and Condensate in the Light-Cone Schwinger Model [PDF]

open access: yes, 1996
The axial anomaly and fermion condensate in the light cone Schwinger model are studied following path integral methods. This formalism allows for a simple and direct calculation for these and other vacuum dependent phenomena.Comment: 10pp ...

The Lamb-Bateman integral equation and the fractional derivatives

open access: yes, 2010
The Lamb-Bateman integral equation was introduced to study the solitary wave diffraction and its solution was written in terms of an integral transform. We prove that it is essentially the Abel integral equation and its solution can be obtained using the
