We’ll beg<strong>in</strong> with the easiest possible example:<br />
GLSM’s are families <strong>of</strong> 2d gauge theories<br />
that RG flow to families <strong>of</strong> CFT’s.<br />
In this case:<br />
NLSM on<br />
P 3 [2,2]<br />
the GLSM for P 3 [2,2] (=T 2 ):<br />
one-parameter<br />
Kahler moduli space<br />
