چکیده

The classification of the equilibrium shapes that a self-gravitating fluid can take in a Riemannian manifold is a classical problem in Mathematical Physics. In this paper it is proved that the equilibrium shapes are isoparametric submanifolds. Some geometric properties of them are also obtained, e.g. classification and existence for some Riemannian spaces and relationship with the isoperimetric problem and the group of isometries of the manifold. Our approach to the problem is geometrical and allows to study the equilibrium shapes on general Riemannian spaces.

A geometric approach to the equilibrium shapes of self-gravitating fluids

The classification of the possible equilibrium shapes that a selfgravitating fluid can take in a Riemannian manifold is a classical problem in mathematical physics. In this paper it is proved that the equilibrium shapes are isoparametric submanifolds. Some geometric properties of the equilibrium shapes are also obtained, specifically the relationship with the isoperimetric problem and the group...

A Comparative Study into “Gere Geometric Designs” in Islamic Architecture and Principle of “Perceptual Creation” in the Mystical Thoughts of Ibn Arabi

This article is an analytic and comparative study into abstract patterns of geometric designs, as one of the most significant spaces in the Islamic architecture, and the principle of perceptual creation. It has a comparative approach to investigate equivalence, effigy, and analogies between the micro and macro systems (in the hierarchical system of the universe). In the mystical cosmology of Ib...

Equilibrium configurations of fluids and their stability in higher dimensions

We study equilibrium shapes, stability and possible bifurcation diagrams of fluids in higher dimensions, held together by either surface tension or self-gravity. We consider the equilibrium shape and stability problem of self-gravitating spheroids, establishing the formalism to generalize the MacLaurin sequence to higher dimensions. We show that such simple models, of interest on their own, als...

Local stability criterion for self-gravitating disks in modified gravity

We study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a Yukawa-like term in the gravitational potential of a point mass. We investigate the effect of such a Yukawa-like term on the dynamics of self-gravitating disks. More specifically, we investigate the consequences of the presence of this term for the local stability of t...

Analysis of Herat embroidery patterns from the perspective of fractal geometry

Geometric shapes and motifs are a combination of the human spiritual mind which sees the existence of beautiful and paints a historical civilization through this vision. The geometric motifs are an expression of the rhythmic and balanced human beings possessions when the human being wants to imagine beyond the present and create a world full of love. The patterns/shapes are the basis of artwork...
