DESCRIPTION:Complex projective varieties with nef anticanonical divisor ap
pear as natural generalisations of Fano varieties. Fano manifolds are clas
sified up to dimension three and many of their properties are well studied
. However\, the classification of manifolds with nef anticanonical divisor
is more complicated as new phenomena arise and many results for Fano mani
folds no longer hold for this class of varieties. In this talk\, we will f
irst look at some examples in dimension two case. Then we will discuss som
e properties of rationally connected threefolds with nef anticanonical div
isor. We will consider the case where the anticanonical divisor is not sem
i-ample\, and by investigating the base locus of the anticanonical system\
, we will give a classification result in this case.\n\nhttps://indico.mat
