## Errata

The errors below are relative to arXiv:1312.2684v2.

 place content thanks to (3.3.2): The RHS is missing $i/(2\pi)$. T. Procházka (4.3.6): $dz/(xz)$ should be $dz/(2xz)$ T. Procházka (4.3.7): $dz/(xz)$ should be $dz/(2xz)$ T. Procházka One line below (4.4.2): The mass term should be $-\int d^2\theta m u$. T. Procházka Two lines below (5.2.5): $\int_{P_0}^P dz/(xz)$ should be $\int_{P_0}^P dz/(2(xz-\Lambda))$. T. Procházka (5.3.1): The discriminant of (5.2.11) is the cube of what was written in (5.3.1). T. Procházka (6.3.6): The RHS should have $1/3!$ in front. T. Procházka (7.1.5): The RHS should have $-1$ in front. T. Procházka Sec.7.3 The mass parameters are all set to zero implicitly. T. Procházka One line below (7.3.7) The last term should be $|\tilde Q_2|^2$. T. Procházka Sec.8.3 and Sec.8.4 The singularities on the $u$-plane of the $N_f=2$ theory are at $u=0$ and $u=-4\Lambda^2$, not at $u=0$ and $u=-\Lambda^2$ as written in many places. T. Procházka (9.1.1): $a_D=\tau_{UV} a$ should be $a_D=2\tau_{UV} a$ Tom Burton (9.1.3): $a_D=\tau_{UV} a$ should be $a_D=2\tau_{UV} a$ Tom Burton One line below (9.1.7) $1-z-f/z$ should be $1-\tilde z-f/\tilde z$. T. Procházka (9.2.16): SU(3)$_D$ should be SU(2)$_D$. S. Nawata Two lines above (9.3.1) A, B, G should be at $z'=\infty,$ $1$, $0$ instead. T. Procházka (9.4.12): The numerator of the second term should be $\mu_1+\mu_2$. T. Procházka The paragraph below (10.1.1): The A-cycle and the B-cycle are around $z=-1$, not around $z=0$. T. Procházka (10.1.6): The RHS should have $+(\delta z)^3$ instead of $-(\delta z)^3$ T. Procházka (10.1.9): The second equation should be $[\delta z]=2/5$ instead of $[\delta x]=2/5$ T. Procházka (10.3.4): The numerator on the RHS should have $1,z,z^2,z^3,z^4$ instead of $1,z,z,z^2,z^3$. T. Procházka (11.1.6): The RHS is missing $i$. T. Procházka A few lines below (11.2.8): $y$ should be $\Lambda^N(z+1/z)$. T. Procházka Footnote 15 attached to (11.2.14): The final $\chi(S)$ should be $\chi(\Sigma)$. T. Procházka (11.3.15): The RHS should have $-1$ in front. T. Procházka (11.5.3): $\tilde u_N$ should be $\delta u_N$. T. Procházka (11.5.10) and (11.5.11): There are various minor mistakes in the computations in these equations and the explanations around it. The result (11.5.12) and the following discussions are OK. T. Procházka One line below (11.5.16): $\delta zdz$ should be $\delta z dx$. T. Procházka One line below (12.1.1): The theory with nonzero $\tilde\mu$ are not superconformal. T. Procházka (12.1.6) and (12.1.8): $\mu'$ needs to be defined as $-(\sum \tilde\mu_i')/N$ with a minus sign in front. T. Procházka (12.1.10): $u_k$ here is a certain dimensionless coefficient times $u_k$ in (12.1.9). T. Procházka (A.1.8): $a$ and $a_D$ on the right hand side should be reversed. J.W. Kim (A.1.9): The first integral should be $\oint_B\lambda \oint_A \partial \lambda/\partial u$. J.W. Kim Two lines below (A.1.9): $\partial \lambda/\partial u=-dz/(2xz)$ should be $\partial \lambda/\partial u=dz/(2xz)$. J.W. Kim (A.1.9): $\partial \lambda/\partial u=-dz/(2xz)=dw + \cdots$ should be $\partial \lambda/\partial u=dz/(2xz)=-dw + \cdots$. J.W. Kim
