==Statement==&lt;br /&gt;
&lt;br /&gt;
This problem asks for the solutions to:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;x^p - y^q = 1&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Here, &amp;lt;math&amp;gt;x,y&amp;lt;/math&amp;gt; are positive integers not equal to &amp;lt;math&amp;gt;0,1&amp;lt;/math&amp;gt; and &amp;lt;math&amp;gt;p,q&amp;lt;/math&amp;gt; are positive integers greater than &amp;lt;math&amp;gt;1&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
[[Catalan&amp;#039;s conjecture]] was that the only solutions to this are &amp;lt;math&amp;gt;x = 3, y = 2, p = 2, q = 3&amp;lt;/math&amp;gt;. This conjecture has been proved.&lt;/div&gt;</summary>
