CPT-symmetry studies with antihydrogen
/ Lehnert, Ralf
Various approaches to physics beyond the Standard Model can lead to small violations of CPT invariance. Since CPT symmetry can be measured with ultrahigh precision, CPT tests offer an interesting phenomenological avenue to search for underlying physics. [...]

Differential geometric mechanisms in Ostrohrads'kyj relativistic spherical top dynamics
/ Matsyuk, R Ya
Some intrinsic tools from the formal theory of variational equations are being demonstrated at work in application to one concrete example of the third-order evolution equation of free relativistic top in three-dimensional space-time. The main goal is to introduce a combined approach consisting in the simultaneous utilization of symmetry principles along with the inverse variational problem considerations in terms of vector-valued differential forms.

The mass function method for obtaining exact solutions of Einstein equations
/ Korkina, Maria ; Kopteva, Elena
We show that the mass function method makes it much easier to obtain the exact solutions of Einstein equations. The known solutions for empty space and for the universe filled with dust-like matter are considered from the point of view of the method and new exact solutions are obtained. [...]
