Proof Analysis

Sara Negri is Docent of Logic at the University of Helsinki. She is the author of Structural Proof Theory (Cambridge University Press, 2001, with Jan von Plato) and she has also written several research papers on mathematical and philosophical logic. Jan von Plato is Professor of Philosophy at the University of Helsinki. He is the author of Creating Modern Probability (Cambridge University Press, 1994), the co-author (with Sara Negri) of Structural Proof Theory (Cambridge University Press, 2001) and has written several papers on logic and epistemology.

"...provide a substantial contribution to the development of proof theory in mathematics.... The book covers a lot of useful material in a concise, efficient and very clearly structured manner. The chapters are written with a palpable intention to show how vast the applicability of the methods is. The results are uniform, general and require a high-level preparation in many different fields. This book can be seen as the stimulating continuation of the authors’ introductory book Structural Proof Theory..." --F.
