Characterization of injective envelopes
Characterization of pointed varieties of universal algebras with normal projections.
Characterization of protomodular varieties of universal algebras.
Characterizations of Lambek-Carlitz type
We give Lambek-Carlitz type characterization for completely multiplicative reduced incidence functions in Möbius categories of full binomial type. The -analog of the Lambek-Carlitz type characterization of exponential series is also established.
Characterizations of some rings with -projective, -(FP)-injective and -flat modules
Let be a commutative ring and a semidualizing -module. We investigate the relations between -flat modules and -FP-injective modules and use these modules and their character modules to characterize some rings, including artinian, noetherian and coherent rings.

Classification of discrete derived categories
The main aim of the paper is to classify the discrete derived categories of bounded complexes of modules over finite dimensional algebras.

Classification of tensor products of symmetric graphs
In the category of symmetric graphs there are exactly five closed tensor products. If we omit the requirement of units, we obtain twelve more.
