*“SymTFTs with Interfaces in Geometric Engineering "*
*
*

_Abstract_

The Symmetry Topological Field Theory (SymTFT) is a powerful framework 
to encode symmetries, anomalies, and global structures of quantum field 
theories. In this talk I will first review its standard construction in 
M-theory geometric engineering on non-compact manifolds with 
torsion-free (co-)homologies. I will then show that in models with 
torsion, the corresponding SymTFTs have interfaces which prevents 
certain defects from ending on the physical boundary — a configuration 
also known as the “club sandwich” in the literature. Finally, I will use 
dualities to argue that such interfaces exist in SymTFTs of so-called 
“frozen” 7d M-theory compactifications, and of 8d IIB/F-theory models 
with O7+ planes.
