To mark the occasion, a Special Issue of Universe has been dedicated to the theoretical aspects of strong gravitational lensing. The articles assembled in this volume contain original research and reviews and apply a variety of mathematical techniques that have been developed to study this effect, both in 3-space and in spacetime. These include: · Mathematical properties of the standard thin lens approximation, in particular caustics; · Optical geometry, the Gauss-Bonnet method and related approaches; · Lensing in the spacetime of general relativity and modified theories; black hole shadows. 517 $aGravitational Lensing and Optical Geometry 606 $aMathematics & science$2bicssc 606 $aResearch & information: general$2bicssc 610 $ablack hole 610 $ablack hole shadow 610 $ablack holes 610 $acaustics 610 $adark matter 610 $aevent horizon telescope 610 $agalaxies 610 $aGauss-Bonnet theorem 610 $ageneral relativity 610 $aglobal monopole 610 $agravitational lens 610 $agravitational lensing 610 $amagnification cross sections 610 $aperfect fluid 610 $arotating black hole 610 $ascalar field 610 $ashadows 610 $astrong gravitational lensing 610 $aultralight particles 610 $aweak deflection 610 $awormhole 610 $awormholes 615 7$aMathematics & science 615 7$aResearch & information: general 700 $aWerner$b Marcus C$4edt$01323014 702 $aWerner$b Marcus C$4oth 906 $aBOOK 912 $a9910557102703321 996 $aGravitational Lensing and Optical Geometry$93035322 997 $aUNINA
