/ Sperling, Marcus ; Steinacker, Harold C.
We consider the SO(4,1) covariant fuzzy hyperboloid Hn4 as a solution of Yang–Mills matrix models, and study the resulting higherspin gauge theory. [...]

Discrete quotients of 3dimensional N = 4 $$ \mathcal{N}=4 $$ Coulomb branches via the cycle index
/ Hanany, Amihay ; Sperling, Marcus
The study of Coulomb branches of 3dimensional N = 4 $$ \mathcal{N}=4 $$ gauge theories via the associated Hilbert series, the socalled monopole formula, has been proven useful not only for 3dimensional theories, but also for Higgs branches of 5 and 6dimensional gauge theories with 8 supercharges.

Intersecting branes, Higgs sector, and chirality from N $$ \mathcal{N} $$ = 4 SYM with soft SUSY breaking
/ Sperling, Marcus ; Steinacker, Harold
We consider SU( N ) N $$ \mathcal{N} $$ = 4 super YangMills with cubic and quadratic soft SUSY breaking potential, such that the global SU(4) R is broken to SU(3) or further. [...]
