SU(3)-structures on quotients of 3-Sasakian orbifolds

Quentin Peres, Dimitrios Tsimpis

We show that if $(S, g, ξ_{i}, η_{i}, Φ_{i})$ is a quasi-regular $3$ -Sasakian orbifold of dimension $7$ , then its quotient $Z$ by one of the Reeb vector fields inherits an $S U (3)$ -structure…

Analytic results for slow-roll curved-space inflation and exponential potentials

Dimitrios Tsimpis, Govind Venugopal

We derive analytic templates for the scalar and tensor primordial power spectra describing cosmologies that transition from kinetic dominance to slow-roll inflation in the presence…
