The conformal null string in and dimensions
Ulf Lindström
In [arXiv:2605.26185 [hep-th]] it is pointed out how the tensionless string with a gauged scale symmetry discussed in the recent articles, [arXiv:2605.12414 [hep-th]], [arXiv:2605.…
Symmetries of tensionless strings
Ulf Lindström
In a recent article, arXiv:2605.12414, it is stated that a certain scale transformation has been "systematically overlooked" in discussions of the tensionless string. Here we point…
The Large Vector Multiplet and Gauging -models
Dmitri Bykov, Ulf Lindström, Martin RoÄek
The Large Vector Multiple (LVM) is the relevant gauge multiplet for gauging isometries acting on both the chiral and the twisted chiral fields in a sigma model. Here we sh…
Superspace Supergravity
Ulf Lindström, Martin RoÄek
We give a brief, incomplete, and idiosyncratic review of the early years of supergravity in superspace as our contribution to the book Half a Century of Supergravity edited by Anna…
