The number of isomorphism classes of (hyper)elliptic curves over a number field with the same discriminant is known to be finite. A more involved task is to count, if not list, all such isomorphism classes. In this talk, we survey old and recent results for elliptic curves. We also explain how one may tackle the same question for genus 2 curves. </div></div></div><div class=""><br class=""></div><div class="">T<span style="font-family: arial, sans-serif;" class="">o attend the meeting online, please use the following link.</span> </div><br class=""><a href="https://sabanciuniv.zoom.us/j/91640295656?pwd=eVY1NzZ3UW8raTlsMk52aThkRjFjZz09" class="">https://sabanciuniv.zoom.us/j/91640295656?pwd=eVY1NzZ3UW8raTlsMk52aThkRjFjZz09</a><br class=""><br class="">Meeting ID: 916 4029 5656<br class="">Passcode: Algebra<br class=""><div class=""><br class=""></div><div class="">Abstracts and forthcoming talks can be found on our webpage <<a href="http://people.sabanciuniv.edu/~mlavrauw/algebra_seminar/sas.html" rel="noreferrer" target="_blank" class="">http://people.sabanciuniv.edu/~mlavrauw/algebra_seminar/sas.html</a>>.<br class=""><br class="">Kind regards,</div><div class="">Michel Lavrauw.</div></body></html>
