Shiftable Heffter spaces
Marco Buratti, Anita Pasotti
The shiftable Heffter arrays are naturally generalized to the shiftable Heffter spaces. We present a recursive construction which starting from a single shiftable Heffter space lea…

More Heffter Spaces via finite fields
Marco Buratti, Anita Pasotti
A Heffter space is a resolvable configuration whose points form a half-set of an abelian group and whose blocks are all zero-sum in . It was recently p…

Heffter Spaces
Marco Buratti, Anita Pasotti
The notion of a Heffter array, which received much attention in the last decade, is equivalent to a pair of orthogonal Heffter systems. In this paper we study the existence problem…
