This paper investigated the periodic and quasi-periodic orbits in the symmetric collinear four-body problem through a variational approach. We analyze the conditions under which homographic solutions minimize the action functional. We compute the min

In this paper, we study the minimizing property for the isosceles trapezoid solutions of the four-body problem. We prove that the minimizers of the action functional restricted to homographic solutions are the Keplerian elliptical solutions, and this

In the current article, we study the kite four-body problems with the goal of identifying global regions in the mass parameter space which admits a corresponding central configuration of the four masses. We consider two different types of symmetrical

The purpose of this paper is to study the phenomenon of lapsed funding that occurs within the public sector using the framework of the Newsvendor Problem. Under this framework, we observe that lapsed funding is a natural outcome of the planning syste

We consider the question of stability for the homographic family of rhombus solutions within the four degree of freedom parallelogram four body problem. Our approach to demonstrate spectral instability for the entire parameter ranges of mass ratio an

In this paper, we prove that the homographic solutions to the rhombus four body problem are the variational minimizers of the Lagrangian action restricted on a holonomically constrained rhombus loop space.
