We have spent so many pages to study $\mathcal{\mathcal{N}}=2$ gauge theories with gauge group $SU\left(2\right)$. In this section we move on to the analysis of larger gauge groups. We will ﬁrst study $SU\left(N\right)$ gauge theories in some detail, and then go on to the case $SO\left(2N\right)$. We also analyze the Argyres-Douglas CFTs obtained from these gauge theories, and show that they are given by the theories ${X}_{N}$ and ${Y}_{N}$ introduced in Sec. 10.5. We close the section by brieﬂy mentioning the Seiberg-Witten solutions to theories with other gauge groups in Sec. 11.6.

The curves that will be presented in this section might not be in the form most commonly found in the older literature. The relation between them would also be explained in Sec. 11.6.
