The Gregory–Laflamme instability (after Ruth Gregory and Raymond Laflamme) is a result in theoretical physics which states that certain black strings and branes are unstable in dimensions higher than four.[1]
In their seminal papers in 1993 and 1994, Gregory and Laflamme showed that certain branes and Higher-dimensional Einstein gravity black string solutions in theories of gravity in higher dimensions are found to exhibit an instability to small perturbations.[2][3][4]
It is very interesting[editorializing] to know the end point of this instability, particularly whether it leads to a phase transition forming a black hole. This has been studied to higher dimensions and a critical dimension has been found to exist below which the end state of instability is a black hole phase, i.e., for . Above the critical dimension the instability drives to a non-uniform black ring phase.[5][6]
