   <dcterms:abstract>We describe the centroid of some Leavitt path algebras. More precisely, for Leavitt&#xd;
path algebras over a field K, we show that if the algebra is simple, then its centroid is&#xd;
isomorphic to K, and if the algebra is prime, then its centroid is also isomorphic to K,&#xd;
except if the graph is a row-finite comet, in which case the centroid is isomorphic to&#xd;
K[x, x−1].</dcterms:abstract>
