The methods involved deep results in algebra and logic, but also many combinatorial insights. Moreover, a result in algorithmic graph theory was one of the two main motivations for the Feder-Vardi conjecture. I will describe this connection and offer personal reminiscences on how it came about. If time permits, I will also discuss some recent work and open problems on other versions of graph dichotomy.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>invitation to the lecture<\/p>\n","protected":false},"author":25,"featured_media":0,"menu_order":0,"template":"","meta":{"_acf_changed":false,"_editorskit_title_hidden":false,"_editorskit_reading_time":0,"_editorskit_is_block_options_detached":false,"_editorskit_block_options_position":"{}"},"categories":[],"tags":[],"tax_aktuality":[],"class_list":["post-69571","cpt_podujatia","type-cpt_podujatia","status-publish","hentry"],"acf":{"acf_link_na_externy_obsah":"","cpt_udalost_datum_konania":"20240523","cpt_udalost_datum_koniec":"20240523","cpt_udalost_miesto_konania":" Jesenn\u00e1 5, videoconference room","cpt_udalost_cas_konania":"14:00:00"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 -
