Simone Costa, Anita Pasotti, Marco Antonio Pellegrini
Relative Heffter arrays, denoted by , have been introduced as a generalization of the classical concept of Heffter array. A is an $…
A generalization of Heffter arrays
Simone Costa, Fiorenza Morini, Anita Pasotti +1
In this paper we define a new class of partially filled arrays, called relative Heffter arrays, that are a generalization of the Heffter arrays introduced by Archdeacon in 2015. Le…

In this paper we study a tour problem that we came cross while studying biembeddings and Heffter arrays, see [D.S. Archdeacon, Heffter arrays and biembedding graphs on surfaces, El…
Strong difference families of special types
Yanxun Chang, Simone Costa, Tao Feng +1
Strong difference families of special types are introduced to produce new relative difference families from the point of view of both asymptotic existences and concrete examples. A…
