Lectures on Mathematical Logic Calculi for Derivations and Deductions

In this volume, logic starts from the observation that in everyday arguments, as brought forward by say a lawyer, statements are transformed linguistically, connecting them in formal ways irrespective of their contents. Understanding such arguments as deductive situations, or "sequents" in the technical terminology, the transformations between them can be expressed as logical rules. The book concludes with the algorithms producing the results of Gentzen's midsequent theorem and Herbrand's theorem for prenex formulas.Felscher, Walter is the author of 'Lectures on Mathematical Logic Calculi for Derivations and Deductions' with ISBN 9789056992675 and ISBN 9056992678.
