DESCRIPTION:Speakers: Alexey Koshelev (Univ. of Beira Interior)\nI will ex
plain how theories with analytic functions of derivatives are\nconnected t
o strings and in particular arise in string field theory\n(SFT) and will s
pent the most part of my talk on the good\nand unrevealed properties of an
alytic infinite derivative (AID) gravity.\nIn particular\, I will discuss
questions of avoiding singularities as\nwell as possible observational evi
dences for such a non-local\nmodification of Einsteinâ€™s theory. Namely\,
imprints in inflationary\nspectra including non-gaussianities. On top of
this I will raise several\npurely mathematical questions which need to be
solved in order to push\nthe physics developments further.\n\nhttps://indi
