DESCRIPTION:Abstract: In 2016, Doran, Harder, and I conjectured a mirror
symmetric relationship between Tyurin degenerations and splittings of cod
imension 1 fibrations on Calabi-Yau manifolds. In this talk I will discuss
recent work to make this conjecture rigorous in the case of K3 surfaces.
I will give a precise definition of what it means for a Tyurin degeneratio
n of K3's to be mirror to a splitting of an elliptically fibred K3, and s
how that this definition enjoys the following compatibilities with existin
g mirror symmetric theories: 1) The general fibre of the Tyurin degenerati
on is mirror to the\n elliptically fibred K3, in the sense of Dolgachev-Ni
kulinĀ 2) Components of the Tyurin degeneration and pieces of the splitting
satisfy a homological version of the (quasi-) Fano-LG correspondenceĀ 3) C
omponents of the Tyurin degeneration which are weak del Pezzo are mirror t
o pieces of the splitting that arise as restrictions of the corresponding
lattice polarised LG models to discs. This is joint work with Luca Giovenz
ana.\n\nHost: Matt Kerr
