curve has bad reduction is known to be finite. Given a prescribed set of prime
integers, S, one may ask how many smooth projective curves with fixed genus
have bad reduction exactly at the primes in S. In this talk, we consider the
question for genus 1 and genus 2 curves when S contains at most 2 primes.
We survey some old and new results on how to list all isomorphism
classes of such curves over the rational field.</span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif"><br></span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif"><br></span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif">----------------------------------------------------------------------------------------------------------------------------</span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif"><br></span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif">Best wishes</span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif"><br></span></font></span></p><p class="MsoNormal" style="margin:0cm 0cm 0.0001pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial;vertical-align:baseline;font-size:11pt;font-family:Calibri,sans-serif"><span style="background-color:rgb(255,255,255)"><font color="#000000"><span style="font-size:9pt;line-height:115%;font-family:Helvetica,sans-serif">Temha</span></font></span></p></div></div>
