Degrees of Freedom in Massive Gravity
D. Comelli, M. Crisostomi, F. Nesti +1
We study in a systematic way a generic nonderivative (massive) deformation of general relativity using the Hamiltonian formalism. The number of propagating degrees of freedom is an…
Spherically Symmetric Solutions in Ghost-Free Massive Gravity
D. Comelli, M. Crisostomi, F. Nesti +1
Recently, a class of theories of massive gravity has been shown to be ghost-free. We study the spherically symmetric solutions in the bigravity formulation of such theories. In gen…
FRW Cosmology in Ghost Free Massive Gravity
D. Comelli, M. Crisostomi, F. Nesti +1
We study FRW homogeneous cosmological solutions in the recently found ghost free massive gravity. In previous works it was shown that when the additional extra metric, needed to ge…
Matrix String Theory and its Moduli Space
G. Bonelli, L. Bonora, F. Nesti +1
The correspondence between Matrix String Theory in the strong coupling limit and IIA superstring theory can be shown by means of the instanton solutions of the former. We construct…
String Interactions from Matrix String Theory
G. Bonelli, L. Bonora, F. Nesti
The Matrix String Theory, i.e. the two dimensional U(N) SYM with N=(8,8) supersymmetry, has classical BPS solutions that interpolate between an initial and a final string configura…
Matrix String Theory, 2D SYM Instantons and affine Toda systems
G. Bonelli, L. Bonora, F. Nesti
Extending a recent result of S.B. Giddings, F. Hacquebord and H. Verlinde, we show that in the U(N) SYM Matrix theory there exist classical BPS instantons which interpolate between…
