A set tiles the integers if and only if the integers can be written as a disjoint union of translates of that set. We consider the problem of finding necessary and sufficient conditions for a finite set to tile the integers. For sets of prime power ลฝ . size, it was solved by D. Newman 1977, J. Numbe

โฆ Synopsis
In this paper , we consider a broad class of simply connected complexes that includes , for example , the face-to-face tilings of E n and S n . Along with a complex (or tiling) we consider a set แซ of qualities that individually can be assigned to the various cells or tiles of the complex , and a group แก which permutes the elements of แซ . These qualities might be colours , a set of positive real numbers or a set of af fine functions . If each ordered pair of adjacent cells is associated with a group element g แก , and a quality q แซ is assigned to any particular cell of the complex , qualities can be assigned to adjacent cells using the action of the group แก on แซ . In fact , since the complex is assumed to be simply connected , a quality can be assigned to any cell of the complex by translating qualities along paths of adjacent cells using the group action .

We study self-dual codes over certain finite rings which are quotients of quadratic imaginary fields or of totally definite quaternion fields over Q. A natural weight taking two different nonzero values is defined over these rings; using invariant theory, we give a basis for the space of invariants
