We will review some recent results (including works related to Fuglede Conjecture) about the tilings of groups. It is unknown whether, for every countable group \\(G\\), any finite subset \\(K\\subset G\\) is contained in a tile of \\(G\\). We prove this for hyperbolic groups (in the sense of Gromov).<\/p>\n    <\/div>\n  <\/div>\n\n  <!-- Footer -->\n  <div class=\"ann-footer\">\n    <span>Mathematics Research Center \u00b7 ASOIU, Baku<\/span>\n    <a href=\"\/seminars\/\">All seminars \u2192<\/a>\n  <\/div>\n\n<\/div><!-- \/.ann-block -->\n<!-- \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\n     END SEMINAR ANNOUNCEMENT\n     \u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550 -->\n\n\n<!-- \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n     BLANK TEMPLATE \u2014 copy this for new announcements\n     \u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500 -->\n<!--\n\n<div class=\"ann-block\" data-type=\"general\">\n\n  <div class=\"ann-topbar\"><\/div>\n\n  <div class=\"ann-logo-row\">\n    <img decoding=\"async\" class=\"ann-logo\" src=\"LOGO_URL_HERE\" alt=\"ASOIU Mathematics Research Center\">\n  <\/div>\n\n  <div class=\"ann-poster\">\n    <div class=\"ann-type\">General Seminar<\/div>\n    <div class=\"ann-poster-rule\"><\/div>\n    <div class=\"ann-title\">\n      TALK TITLE HERE\n    <\/div>\n    <div class=\"ann-speaker\">Speaker Name<\/div>\n    <div class=\"ann-affil\">Institution<\/div>\n  <\/div>\n\n  <div class=\"ann-meta\">\n    <div class=\"ann-meta-item\">\n      <svg viewBox=\"0 0 16 16\" fill=\"currentColor\"><path d=\"M7 0H2a1 1 0 00-1 1v2h14V1a1 1 0 00-1-1H7zm7 4H1v10a1 1 0 001 1h12a1 1 0 001-1V4z\"\/><\/svg>\n      <span><span class=\"ann-meta-label\">Date&nbsp;<\/span>Month DD, YYYY<\/span>\n    <\/div>\n    <div class=\"ann-meta-item\">\n      <svg viewBox=\"0 0 16 16\" fill=\"currentColor\"><path d=\"M8 1a5 5 0 100 10A5 5 0 008 1zM0 8a8 8 0 1116 0A8 8 0 010 8z\"\/><path d=\"M7.5 4.5v4l2.5 1.5.5-.87L8.5 8V4.5z\"\/><\/svg>\n      <span><span class=\"ann-meta-label\">Time&nbsp;<\/span>HH:MM<\/span>\n    <\/div>\n    <div class=\"ann-meta-item\">\n      <svg viewBox=\"0 0 16 16\" fill=\"currentColor\"><path d=\"M8 0C5.24 0 3 2.24 3 5c0 3.75 5 11 5 11s5-7.25 5-11c0-2.76-2.24-5-5-5zm0 7.5a2.5 2.5 0 110-5 2.5 2.5 0 010 5z\"\/><\/svg>\n      <span><span class=\"ann-meta-label\">Location&nbsp;<\/span>Room \/ Online<\/span>\n    <\/div>\n  <\/div>\n\n  <div class=\"ann-abstract\">\n    <div class=\"ann-abstract-label\">Abstract<\/div>\n    <div class=\"ann-abstract-body\">\n      <p>Abstract text here.
