Homotopy analysis method for solving fuzzy Nonlinear Volterra integral equation of the second kind

Iraqi Journal for Computer Science and Mathematics
This paper introduces the homotopy analytic HAM, an effective and reliable method for solving computationally challenging fuzzy Volterra nonlinear integral equations of the second type. Numerical examples are provide to demonstrate the accuracy of  HAM.

Two Models for the Homotopy Theory of Cocomplete Homotopy Theories

, 2014
We prove that the homotopy theory of cofibration categories is equivalent to the homotopy theory of cocomplete quasicategories. This is achieved by presenting both homotopy theories as fibration categories and constructing an explicit equivalence between them.

Lorentz covariance of the 4d nonlinear higher-spin equations via BRST

Physics Letters B
We propose a BRST extension of the higher-spin gauge theory in AdS4 with the BRST operator associated with the local Lorentz symmetry. Our construction supports manifest local Lorentz covariance and is applicable both to any homotopy scheme of the ...

Lifting Properties for A-Homotopy Theory

Contributions to Discrete Mathematics
In classical homotopy theory, two spaces are considered homotopy equivalent if one space can be continuously deformed into the other. This theory, however, does not respect the discrete nature of graphs. For this reason, a discrete homotopy theory that recognizes the difference between the vertices and edges of a graph was invented, called A-homotopy ...

Out-of-time-order asymptotic observables are quasi-isomorphic to time-ordered amplitudes

Journal of High Energy Physics
Asymptotic observables in quantum field theory beyond the familiar S-matrix have recently attracted much interest, for instance in the context of gravity waveforms.
