Using methods of statistical physics, we study the average number and kernel size of general sparse random matrices over Galois fields, with a given connectivity profile, in the thermodynamical limit of large matrices. We introduce a mapping ofmatrices onto spin systems using the representation of the cyclic group of orderas theth complex roots of unity. This representation facilitates the derivation of the average kernel size of random matrices using the replica approach, under the replica-symmetric ansatz, resulting in saddle point equations for general connectivity distributions. Numerical solutions are then obtained for particular cases by population dynamics. Similar techniques also allow us to obtain an expression for the exact and average numbers of random matrices for any general connectivity profile. We present numerical results for particular distributions.
