First order deformations of schemes with normal crossing singularities
Nikolaos Tziolas
We describe the sheaf T^1(X) of first order deformations of a reduced scheme with normal crossing singularities. In particular, we obtain a formula for T^1(X) in a suitable log res…

Smoothings of Fano varieties with normal crossing singularities
Nikolaos Tziolas
This paper obtains criteria for a Fano variety X with normal crossing singularities defined over an algebraically closed field of characteristic zero, to be smoothable. The differe…
