On the apparent lack of any de Sitter spacetime-perturbative string theory vacua (Danielsson-VanRiet 18)
On de Sitter spacetimes in the landscape of string theory vacua (or not):
Specifically on de Sitter spacetime cosmology brane world models in ambient AdS-bulk spacetime:
Souvik Banerjee, Ulf Danielsson, Giuseppe Dibitetto, Suvendu Giri, Marjorie Schillo, Emergent de Sitter cosmology from decaying AdS (arXiv:1807.01570)
Souvik Banerjee, Ulf Danielsson, Giuseppe Dibitetto, Suvendu Giri, Marjorie Schillo, de Sitter Cosmology on an expanding bubble (arXiv:1907.04268)
On D6-branes/KK-monopoles in M-theory discussed via G-structure:
On the swampland:
Ulf Danielsson, The quantum swampland (arXiv:1809.04512)
(argues that the issue with stringy de Sitter moduli stabilization raised in Sethi 17 is related to the de Sitter instability seen in QFT, according to the references above)
