<div align="left"><b><b><font color="#ff0000">Abstract:</font></b></b><font
color="#ff0000"><font color="#000000"> A μ-stable vector bundle
E of rank 2 with c1(E)=0 on P3 is called mathematical
instanton bundle if H1(P3,E(−2))=0. In this talk, we will
study the definiton of mathematical instanton bundles on Fano
3-folds and the construction of them on P1×F1 where F1 is the
del Pezzo surface of degree 8. This talk is based on the joint
work with Vincenzo Antonelli and Gianfranco Casnati.<br>
