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.\u003c\/p\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 128\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.5 x 9.61 x 6.69 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e December 08, 2020\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":47337033924857,"sku":"9783039432868","price":54.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/2782\/3097\/files\/Nj6AlXRNTk9783039432868.webp?v=1769674671","url":"https:\/\/bookscloud.io\/products\/gravitational-lensing-and-optical-geometry-a-centennial-perspective-hardcover","provider":"BooksCloud Book Dropshipping","version":"1.0","type":"link"}
