==Definition==&lt;br /&gt;
&lt;br /&gt;
Let &amp;lt;math&amp;gt;M&amp;lt;/math&amp;gt; be a [[differential manifold]] and &amp;lt;math&amp;gt;E&amp;lt;/math&amp;gt; a [[vector bundle]] over &amp;lt;math&amp;gt;M&amp;lt;/math&amp;gt;.

&lt;br /&gt;
* For every open subset &amp;lt;math&amp;gt;U&amp;lt;/math&amp;gt; of &amp;lt;math&amp;gt;M&amp;lt;/math&amp;gt;, the object associated to &amp;lt;math&amp;gt;E&amp;lt;/math&amp;gt; is the [[connection algebra]] associated to the restriction of &amp;lt;math&amp;gt;E&amp;lt;/math&amp;gt; to a vector bundle over &amp;lt;math&amp;gt;U&amp;lt;/math&amp;gt;&lt;br /&gt;
* The restriction map is defined as follows: {{fillin}}&lt;br /&gt;
&lt;br /&gt;
Sometimes the &amp;#039;&amp;#039;&amp;#039;sheaf of connection algebras&amp;#039;&amp;#039;&amp;#039; is termed the connection algebra, though the latter term is sometimes used for the &amp;#039;&amp;#039;global object&amp;#039;&amp;#039;.&lt;/div&gt;</summary>
