Query: Isoperimetric problem in H-type groups and Grushin spaces   We study the isoperimetric problem in H-type groups and Grushin spaces,
emphasizing a relation between them. We prove existence, symmetry and
regularity properties of isoperimetric sets, under a symmetry assumption that
depends on the dimension.
