<p style="margin-bottom: 0in; line-height: 100%; orphans: 2; widows: 2;" align="left">CiE 2021 is the seventeenth conference organized by the Association Computability in Europe. The /Computability in Europe/ conference (CiE) series has built up a strong tradition for developing a scientific program which is interdisciplinary at its core bringing together all aspects of computability and foundations of computer science, as well as the interplay of these theoretical areas with practical issues in CS and other disciplines such as biology, mathematics, history, philosophy, and physics. For more information about the CiE conferences and the Association CiE, please have a look at: <a href="https://www.acie.eu/"><span style="color: #000080;"><u>https://www.acie.eu/</u></span></a>. <br /><br /></p>
<p style="margin-bottom: 0in; line-height: 100%; orphans: 2; widows: 2;" align="left">CiE 2021 will be the second CiE conference that is organized as a virtual event and aims at a high-quality meeting that allows and invites active participation from all participants.<span style="color: #ff0000;"> </span>It will be hosted virtually by Ghent University.</p>
<p style="margin-bottom: 0in; line-height: 100%; orphans: 2; widows: 2;" align="left"><br />Previous meetings have taken place in Amsterdam (2005), Swansea (2006), Siena (2007), Athens (2008), Heidelberg (2009), Ponta Delgada (2010), Sofia (2011), Cambridge (2012), Milan (2013), Budapest (2014), Bucharest (2015), Paris (2016), Turku (2017), Kiel (2018), Durham (2019) and virtually in Salerno<span style="color: #ff0000;"> </span>(2020)</p>

The Programme Committee cordially invites all researchers (European and non-European) to submit their abstract for informal presentations. The abstract will be posted on the CiE 2021 website. </span></span></span></p>
