Tóm tắt: We discuss the celebrated theorem of Beauville and Laszlo on formal glueing of sheaves. More precisely, let X be a scheme, Z a closed subscheme and X^ the formal completion of X along Z. Then Beauville-Laszlo theorem explains when one can glue sheaves on X^ and U to get a sheaf on X. Some generalizations and applications are also discussed.
