Affine homogeneous varieties and suspensions [PDF]

open access: yesResearch in the Mathematical Sciences 11 (2024), no. 2, article 27, 2023
An algebraic variety $X$ is called a homogeneous variety if the automorphism group $\mathrm{Aut}(X)$ acts on $X$ transitively, and a homogeneous space if there exists a transitive action of an algebraic group on $X$. We prove a criterion of smoothness of a suspension to construct a wide class of homogeneous varieties.

Cosmological consequences of a rolling homogeneous scalar field.

open access: yesPhysical Review D, Particles and fields, 1988
The cosmological consequences of a pervasive, rolling, self-interacting, homogeneous scalar field are investigated. A number of models in which the energy density of the scalar field red-shifts in a specific manner are studied.

Verification of Human Lumbar Vertebrae and Intervertebral Disc Finite Element Models under Mechanical Forces

open access: yesASM Science Journal, 2021
Bone, being nonhomogeneous in nature need a complicated and time-consuming process to undergo computed simulation like finite element analysis. To overcome this hurdle, assuming a nonhomogeneous model as homogeneous could be a solution.

Nonisothermal homogeneous nucleation [PDF]

open access: yes, 1992
Classical homogeneous nucleation theory is extended to nonisothermal conditions through simultaneous cluster mass and energy balances. The transient nucleation of water vapor following a sudden increase in saturation ratio is studied by numerically ...
