The Hexablock: a domain associated with the $\mu$-synthesis in $M_2(\mathbb{C})$

Indranil Biswas, Sourav Pal, Nitin Tomar

We introduce a domain named \textit{hexablock} in ${\mathbb{C}}^4$ and show that its origin is a special case of $\mu$-synthesis in $M_2(\mathbb{C})$, more precisely the ${\mu }_E$-unit ball…
