From static to cosmological solutions of $$ \mathcal{N} $$ = 2 supergravity
From static to cosmological solutions of $$ \mathcal{N} $$ = 2 supergravity
A bstract We obtain cosmological solutions with Kasner-like asymptotics in $$ \mathcal{N} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>N</mml:mi> </mml:math> = 2 gauged and ungauged supergravity by maximal analytic continuation of planar versions of non-extremal black hole solutions. Initially, we construct static solutions with planar symmetry by solving the time-reduced field equations. Upon …
