TCFT from N = (2, 2) by twisting<br />
• Positive B-twist<br />
• Gives TCFT with c = 0<br />
T +<br />
twisted (z) = T (z) + 1 2 ∂U(z) ,<br />
¯T +<br />
twisted (¯z) = ¯T (¯z) + 1 2 ¯∂Ū(¯z) .<br />
• ∆(G + , G − , U) = (3/2, 3/2, 1) ↦→ (1, 2, 1)<br />
• G + ↦→ Q<br />
• Chiral ring maps to cohomology<br />
• G − cohomology partner to T +<br />
twisted<br />
• U partner to Q<br />
