Isomonodromy Deformations at an Irregular Singularity with Coalescing Eigenvalues

Cotti, Giordano; Dubrovin, Boris; Guzzetti, Davide (2017)

We consider an n×n linear system of ODEs with an irregular singularity of Poincar\'e rank 1 at z=∞, holomorphically depending on parameter t within a polydisc in Cn centred at t=0. The eigenvalues of the leading matrix at ...
Local moduli of semisimple Frobenius coalescent structures

Cotti, Giordano; Dubrovin, Boris; Guzzetti, Davide (SISSA, 2018-01)

There is a conjectural relation, formulated by the second author, between the enumerative geometry of a wide class of smooth projective varieties and their derived category of coherent sheaves. In particular, there is an ...
