We study the Luna slice theorem in the case of quivers with an involution or supermixed quivers as introduced by Zubkov in [6]. We construct an analogue to the notion of a local quiver setting described in [3]. We use this technique to determine dimension vectors of simple supermixed representations.

Research and practice experience shows that indigenous and non-indigenous women throughout Mexico continue to seek the services of midwives and out-of-hospital care, regardless of the improvements in access to public services. This observation alone raises important questions about the divide between the type of public services available to indigenous and low-income women, and their needs and d...
