"Classification of kinematic self-similar solutions of bulk-viscous, 
spherically symmetric spacetimes”


címmel tartandó szemináriumára.


Kivonat:



The scale-free nature of gravitational interaction in both Newtonian gravity 
and the general theory of relativity gives rise to the concept of 
self-similarity, where solutions are scale invariant. As a result of this 
property, the governing partial differential equations are greatly simplified 
and can be transformed into ordinary ones. These solutions function as 
attractors, characterizing the asymptotic dynamics of more general solutions. 
There exist situations in which self-similarity is only partially realized, 
giving rise to kinematic self-similar solutions. Our study provides a 
systematic classification of kinematic self-similar solutions corresponding 
to the most general spherically symmetric space-time in the presence of bulk 
viscous flows.
