This textbook presents the principles of functional analysis in a clear and concise way. The first three chapters describe the general notions of distance, integral, and norm, as well as their relations. Fundamental examples are provided in the three chapters that follow: Lebesgue spaces, dual spaces, and Sobolev spaces. Two subsequent chapters develop applications to capacity theory and elliptic problems. In particular, the isoperimetric inequality and the Polya-Szego and Faber-Krahn inequalities are proved by purely functional methods. The epilogue contains a sketch of the history of functional analysis in relation to integration and differentiation. Starting from elementary analysis and introducing relevant research, this work is an excellent resource for students in mathematics and applied mathematics. The second edition of Functional Analysis includes several improvements as well as the addition of supplementary material. Specifically, the coverage of advanced calculus and distribution theory has been completely rewritten and expanded. New proofs, theorems, and applications have been added as well for readers to explore.

Willem's book is devoted to minimax theorems and their applications to partial differential equations. Presenting basic minimax theorems in a simple and unified way, this book may serve as a textbook for advanced graduate students in partial differential equations.

Early Modern Drama in Performance is a collection of essays in honor of Lois Potter, the distinguished author of five monographs, including most recently The Life of William Shakespeare (2012), and numerous articles, edited collections, and editions. This collection's emphasis on Shakespearean and early modern drama reflects the area for which Potter is most widely known, as a performance critic, editor, and literary scholar. The essays by a diverse group of scholars who have been influenced by Potter address recurring themes in her work: Shakespeare and non-Shakespearean early modern drama, performance history and theatre practice, theatrical performance across cultures, play reviewing, and playreading. What unifies them most, though, is that they carry on the spirit of Potter's work: her ability to meet a text, a performance, or a historical period on its own terms, to give scrupulous attention to specific details and elegantly show how these details generate larger meaning, and to recover and preserve the fleeting and the ephemeral.

The goal of this work is to present the principles of functional analysis in a clear and concise way. The first three chapters of Functional Analysis: Fundamentals and Applications describe the general notions of distance, integral and norm, as well as their relations.

Many boundary value problems are equivalent to Au=O (1) where A: X ---+ Y is a mapping between two Banach spaces. When the problem is variational, there exists a differentiable functional 0 and e E X such that lIell > rand inf"

This book explores interconnections between voyage narratives and travel plays in a period of intense foreign relations and the incipient colonization of the New World. Eminent Renaissance scholars use historical inquiry and textual analysis to offer readings of narrative and dramatic texts, envisaged both in the context of the period and from the far-reaching perspective of Britain's cultural history. Plays like The Spanish Tragedy, Doctor Faustus, Eastward Ho! or The Tempest - itself the subject of three chapters - are discussed alongside relatively obscure works. The plays are never approached as mere cultural documents. The underlying assumption is that the theatre is not reducible to a medium for conflicting ideologies but should be viewed as a privileged site of various meanings, of roads leading in several directions.

George Lyman Kittredge's insightful editions of Shakespeare have endured in part because of his eclecticism, his diversity of interests, and his wide-ranging accomplishments--all of which are reflected in the valuable notes in each volume. The plays in the New Kittredge Shakespeare series retain their original Kittredge notes and introductions, changed or augmented only when some modernization seems necessary. These new editions also include introductory essays by contemporary editors, notes on the plays as they have been performed on stage and film, and additional student materials. These plays are being made available by Focus Publishing with the permission of the Kittredge heirs.
