• Deformation parameter<br />
Fix deformations<br />
a 0 = span{x αα , ∑ α<br />
x αα }<br />
a = p αα x αα + q ∑ α<br />
x αα<br />
• Twist<br />
T +<br />
twisted = T N =(2,2)<br />
a + 1 2 ∂U a<br />
• p αα fixed by<br />
T +<br />
twisted = T GL(N|N)<br />
• The single remaining parameter q fixed by<br />
G + a is fermionic current<br />
• c = 3N 2 ↦→ c a = 0 (before twisting)<br />
• Whole deformation can be seen as background charge
