Based on the conceptual representation of objects in space and time as introduced in Temporal Concept Analysis first steps are done into the direction of a conceptual theory of ...
We present a uniform relational framework for developing proof systems for theories of manyvaluedness that may have the form of a logical system, of a class of algebra or of an in...
A notion called Herbrand saturation is shown to provide the modeltheoretic analogue of a proof-theoretic method, Herbrand analysis, yielding uniform model-theoretic proofs of a nu...
In this concluding synthesis article, I summarize and discuss the papers that comprise both parts of this special issues. Two organizing frameworks are provided to facilitate read...
This paper presents Automath encodings (which also are valid in LF/P) of various kinds of foundations of mathematics. Then it compares these encodings according to their size, to f...
