On a conjecture concerning minus parts in the style of Gross
This paper is devoted to Gross's conjecture on tori over the base field Q. We call it the Minus Conjecture, since it involves a regulator built from units in the minus part. We recall and develop its relation to a ...

The Minus Conjecture revisited
In an earlier paper we proved some results concerning Gross's conjecture on tori. This conjecture, which we call the Minus Conjecture, is closely related to a conjecture of Burns, which is now kno...

Embedded BHs and multipole globules: clustered misaligned thick accretion disks around static SMBHs
We investigate clusters of misaligned (inclined) tori orbiting a central static, pressure supported, perfect fluid tori analyzing purely hydrodynamic models. We study the tori collision emergence and, consequently, the stab...

Influence of toroidal magnetic field in multiaccreting tori
of several magnetized accretion tori, dubbed as ringed accretion discs (RADs), orbiting around one central Kerr supermassive black hole (SMBH) in active galactic nuclei on tori formation and emergence of RADs instabilities...

Charged Tori in Spherical Gravitational and Dipolar Magnetic Fields
A Newtonian model of non-conductive, charged, perfect fluid tori orbiting and stationary, axisymmetric toroidal structures are analyzed. Matter in such tori exhibits existence of off-equatorial charged tori and equatorial <...
