正New Partial Geometric Difference Sets and Partial Geometric Difference Families Jerod MICHELAbstract Using Galois rings and Galois fields,we construct several infinite classes of partial geometric difference sets,and partial geometric difference families,with new parameters.Furthermore,these partial geometric difference sets(and partial geometric difference families)
