Gauge invariant description of weak gravitational field on a spherically symmetric background with cosmological constant
Jacek Jezierski, Piotr Waluk
We present a formalism for analysis of linear Cauchy data on a Kottler metric. Our method removes redundancy due to gauge transformations and constraints. A set of four gauge-invar…

Simple description of generalized electromagnetic and gravitational hopfions
Tomasz Smołka, Jacek Jezierski
The generalization of electromagnetic and gravitational hopfions is performed in terms of a complex scalar field. New definition of topological charge for linearized gravity is giv…
