Abstract
A category PAlg(τ) of partial algebras of a given type τ will be introduced. Then we will present a categorical concept in order to characterize those subcategories of PAlg(τ), which are closed under the formation of various kinds of subobjects. We will also give a characterization for bireflective subcategories of PAlg(τ), which enables us to show, that the subcategory Alg(τ) consisting of all total algebras of type τ is the smallest bireflective subcategory of PAlg(τ).
