|TITLE||Extended Topological Field Theories.|
|ABSTRACT||ETFT is another mathematical formalism which tries to explain QFT.
But, it is hard to expect that it can explain QFT since ETFT are only using topology and higher category structure.
Recently, Jacob Lurie's team proved that some ETFT can explain some factorization algebras which can explain chiral algebras.
I will try to explain some of mathematical ingredients.
