First-order reduction

In computer science, a first-order reduction is a very weak type of reduction between two computational problems in computational complexity theory. A first-order reduction is a reduction where each component is restricted to be in the class FO of problems calculable in first-order logic. Since we have , the first-order reductions are weaker reductions than the logspace reductions.
