A proposal is made for a cosmological D3-D7 model with a constant magnetic flux along the D7 world volume. It describes an $\mathcal{N}=2$ gauge model with Fayet-Iliopoulos terms and the potential of the hybrid P-term inflation. The motion of the D3-brane towards D7 in a phase with spontaneously broken supersymmetry provides a period of slow-roll inflation in the de Sitter valley, the role of the inflaton being played by the distance between D3- and D7-branes. After tachyon condensation a supersymmetric ground state is formed: a D3-D7 bound state corresponding to an Abelian non-linear (non-commutative) instanton. In this model the existence of a non-vanishing cosmological constant is associated with the resolution of the instanton singularity. We discuss a possible embedding of this model into a compactified M-theory setup.

- Problems with Tachyon Inflation (2002, background): “Significant progress in was achieved in [6, 7] for the second class of brane inflation models, where instead of brane-antibrane annihilation the authors considered BPS branes either at small angles [6] or in the presence of small background fields [7].”
- On Inflation in String Theory (2003, methodology): “The D3/D7 brane inflation model [ 19 , 20, 84] is a stringy version of the Dterm inflation in supergravity.”
- Loop corrections to volume moduli and inflation in string theory (2004, background): “Thus, the three questions above can be addressed simultaneously by calculating the gauge kinetic function of the D7-branes at the open-string one-loop level.”
- On brane inflation with volume stabilization (2003, methodology): “An important difference in our setting is that we derived the condition of shift symmetry of the effective N = 1 supergravity as a consequence of our requirement to describe the BPS branes using effective field theory [3, 13].”

- Inflation and String Theory (2014, background): “—If the dominant force on the D3-brane comes from interactions with supersymmetry-breaking fluxes on a D7brane, as in [609], then the potential can be fine-tuned to have an inflationary inflection point, with phenomenology broadly similar to that described in §5.”
