This book constitutes the refereed post-proceedings of the Second International Workshop on Foundational and Practical Aspects of Resource Analysis, FOPARA 2011, held in Madrid, Spain, in May 2011. The 8 revised full papers were carefully reviewed and selected from the papers presented at the workshop and papers submitted following an open call for contributions after the workshop. The papers are organized in the following topical sections: implicit complexity, analysis and verfication of cost expressions, and worst case execution time analysis.

This book constitutes the refereed proceedings of the Second International Conference on Interactive Theorem proving, ITP 2011, held in Berg en Dal, The Netherlands, in August 2011.
The 25 revised full papers presented were carefully reviewed and selected from 50 submissions. Among the topics covered are counterexample generation, verification, validation, term rewriting, theorem proving, computability theory, translations from one formalism to another, and cooperation between tools. Several verification case studies were presented, with applications to computational geometry, unification, real analysis, etc.

This book constitutes the proceedings of the 4th International Workshop on Foundational and Practical Aspects of Resource Analysis, FOPARA 2015, held in London, UK, in April 2015. The 6 papers presented in this volume were carefully reviewed and selected from 7 submissions.
