BPS Bounds for Worldvolume Branes
Jerome P. Gauntlett, Joaquim Gomis, Paul K. Townsend
The worldvolume field equations of M-branes and D-branes are known to admit p-brane soliton solutions. These solitons are shown to saturate a BPS-type bound on their p-volume tensi…
M-theory from its superalgebra
P. K. Townsend
These lectures explore what can be learnt about M-theory from its superalgebra. The first three lectures introduce the 'basic' branes of M-theory, and type II superstring theories,…
M-brane intersections from worldvolume superalgebras
Eric Bergshoeff, Joaquim Gomis, Paul K. Townsend
It is known that the M-branes of M-theory correspond to p-form charges in the D=11 spacetime supersymmetry algebra. Here we show that their intersections are encoded in the p-form…
Supersymmetry of M-Branes at Angles
Nobuyoshi Ohta, Paul K. Townsend
We determine the possible fractions of supersymmetry preserved by two intersecting M-5-branes. These include the fractions 3/32 and 5/32 which have not occurred previously in inter…
M-theory superalgebra from the M-5-brane
Dmitri Sorokin, Paul K. Townsend
The algebra of Noether supercharges of the M-5-brane effective action is shown to include both 2-form and 5-form central charges. Surprisingly, only the 5-form charge is entirely d…
Black Holes
P. K. Townsend
Lecture notes for a 'Part III' course 'Black Holes' given in DAMTP, Cambridge. The course covers some of the developments in Black Hole physics of the 1960s and 1970s.
