<p><font face="Times New Roman, Times, serif"> <b>Abstract:
</b>Based on joint work with Meng Cheng
(arXiv:2211.12543), we will discuss some
aspects of global symmetries and their ‘t
Hooft anomalies.<br>
<br>
We will define a notion of an emanant global
symmetry. It is not a symmetry of the UV
theory, but unlike emergent (accidental)
symmetries, it is not violated by any
relevant or irrelevant operators in the IR
theory.<br>
<br>
We will present lattice models with
anomalous internal symmetries and see how
the anomalies are diagnosed on the lattice
using topological defects.<br>
<br>
We will also discuss lattice models with
anomalous lattice translation and relate
them to an anomalous emanant symmetry in the
IR theory. This will connect our discussion
to the well-known Lieb-Schultz-Mattis
theorem and to filling constraints like
Luttinger theorem.</font></p>
