Non-solvability in the flat category of elliptic operators with real analytic coefficients
Martino Fassina, Yifei Pan
Let , be an open set. For an elliptic differential operator on with real analytic coefficients and a point , we construct a smooth fun…
An extension theorem for regular functions of two quaternionic variables
Luca Baracco, Martino Fassina, Stefano Pinton
For functions of two quaternionic variables that are regular in the sense of Fueter, we establish a result similar in spirit to the Hanges and Trèves theorem. Namely, we show that…
On the Ekeland-Hofer symplectic capacities of the real bidisc
Luca Baracco, Martino Fassina, Stefano Pinton
In with the standard symplectic structure we consider the bidisc constructed as the product of two open real discs of radius . We compute explicit…
A remark on two notions of order of contact
Martino Fassina
We recall two measurements of the order of contact of an ideal in the ring of germs of holomorphic functions at a point and we provide a class of examples in which they differ.
