Let h j : V → R, j = 1, . . . , n, be Hermitian forms on a inner product space over F = C or H, and let h : V → R n have j th component h j . We study path connectedness of the joint zero set h -1 (0) ∩ V 1 and convexity of the joint range h(V 1 ) for various values of n, where V 1 is the unit spher
