Non-homothetic preferences, optimal public finance policy, and structural transformation

Cogent Economics & Finance
This study uses a comparative perspective to investigate how fiscal policies and budgetary mechanisms influence structural economic changes. By constructing a theoretical model rooted in the government’s non-homothetic preferences, we analyze how fiscal ...

Closed Form Solution in the Buckling Optimization Problem of Twisted Shafts

Applied Mechanics, 2023
The counterpart for Euler’s buckling problem is Greenhill’s problem, which studies the forming of a loop in an elastic beam under torsion. In the context of twisted shafts, the optimal shape of the beam along its axis is searched.

A Short Note on a Mus-Cheeger-Gromoll Type Metric

Journal of New Theory, 2023
In this paper, we first show that the complete lift $U^{c}$ to $TM$ of a vector field $U$ on $M$ is an infinitesimal fiber-preserving conformal transformation if and only if $U$ is an infinitesimal homothetic transformation of $(M,g)$.

Quasi-homothetic transformation for comparing the mechanical performance of planar models in biological research  [PDF]

, 2013
The potential of Finite Element Analysis (FEA) as an analytical technique in biological research has been widely highlighted in recent years. In spite of its great power, only in the best of circumstances one can compare the behaviour of models that ...

Building test data from real outbreaks for evaluating detection algorithms. [PDF]

PLoS ONE, 2017
Benchmarking surveillance systems requires realistic simulations of disease outbreaks. However, obtaining these data in sufficient quantity, with a realistic shape and covering a sufficient range of agents, size and duration, is known to be very ...

Conformal vector fields on f-cosymplectic manifolds

Filomat, 2023
In this paper, at first we characterize f-cosymplectic manifolds admitting conformal vector fields. Next, we establish that if a 3-dimensional f -cosymplectic manifold admits a homothetic vector field V, then either the manifold is of constant ...

The Maxwell Lagrangian in purely affine gravity [PDF]

, 2008
The purely affine Lagrangian for linear electrodynamics, that has the form of the Maxwell Lagrangian in which the metric tensor is replaced by the symmetrized Ricci tensor and the electromagnetic field tensor by the tensor of homothetic curvature, is ...
