This paper applies the first-order Seiberg–Witten map to evaluate the first-order noncommutative Kerr tetrad. The classical tetrad is taken to follow the locally non-rotating frame prescription. We also evaluate the tiny effect of non-commutativity on the efficiency of the Penrose process of rotational energy extraction from a black hole.

Abstract
This paper applies the first-order Seiberg–Witten map to evaluate the first-order noncommutative Kerr tetrad. The classical tetrad is taken to follow the locally non-rotating frame prescription. We also evaluate the tiny effect of non-commutativity on the efficiency of the Penrose process of rotational energy extraction from a black hole.File in questo prodotto:
