&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;In [[mathematics]] and [[physics]], '''Penrose graphical notation''' or '''tensor diagram notation''' is a (usually handwritten) [[Mathematical diagram|visual depiction]] of [[Multilinear function|multilinear functions]] or tensors proposed by [[Roger Penrose]].&lt;br /&gt;
&lt;br /&gt;
== Description ==&lt;br /&gt;
&lt;br /&gt;
A diagram in the notation consists of several shapes linked together by lines.&lt;br /&gt;
&lt;br /&gt;
The notation has been studied extensively by [[Predrag Cvitanović]], who used it to classify the classical [[Lie groups]].&lt;br /&gt;
&lt;br /&gt;
It has also been generalized using [[representation theory]] to spin networks in physics, and with the presence of matrix groups to trace diagrams in [[linear algebra]].&lt;br /&gt;
