Using the idea of Halpern iteration, we prove a strong convergence theorem for finding a common fixed point of an infinite family of demimetric mappings in a Hilbert space. Using this result, we obtain well-known and new strong convergence theorems in a Hilbert space.

Keywords: Common fixed point, demimetric mapping, metric projection, inverse strongly monotone mapping, Halpern iteration.
