Abstract. We study a weakening of the notion of logical relations, called prelogical relations, that has many of the features that make logical relations so useful but having furth...
The ordered conjecture states that least fixed-point logic LFP is strictly more expressive than first-order logic FO on every infinite class of ordered finite structures. It has b...
