WILSON 375 Preface The 1998 AMS Winter Meeting in Baltimore was the occasion for a series of special sessions in homotopy theory honoring our colleague J. Michael Boardman on his 60th birthday, and this volume has grown from that beginning. We hope it reflects the influence of his thinking and his personality. Mike is famous for his reticence and his wit. Having created modern stable homotopy theory with his Warwick notes, he has been content to leave them un- published. We are proud to have used this volume as the occasion to bring his classic work on conditionally convergent spectral sequences into print. His thesis on the foundations of Thorn's theory of singularities is a cornerstone of that subject, and much of modern differential topology and K-theory rest on the Boardman-Vogt theory of homotopy-everything H -spaces. One of our goals in this volume has been to show how the trees Mike planted have grown. More than fifty people spoke in the series of special sessions, but one afternoon was explicitly devoted to capturing some of the history of algebraic topology in the 60's and 70's; this volume begins with those accounts. The bulk of this festschrift, however, consists of research papers, which we hope will give some sense of the vitality of the theory of 'homotopy-invariant algebraic structures'. It was on Mike's watch that homotopy theory became autonomous: the notion that geometric objects can be modelled by algebraic structures goes back to the Renaissance, but at some point in the sixties people began to sense the possibility of thinking of spaces themselves as algebraic objects. Frank Adams demonstrated very convincingly the power of homological algebra in stable categories, and Quillen showed that many problems previously regarded as pure algebra were in fact pro- foundly homotopy-theoretic in nature. Much of Mike's work has been concerned with developing the quite subtle ways of thinking needed to do algebra in homo- topy categories; one line of descent leads from that work to Waldhausen's brave new rings, but others lead to other applications, from operads to logic. It is our pleasure and our good fortune to be Mike Boardman's colleagues. We present this volume in his honor and hope that it reflects the respect of his many friends who attended the conference or submitted papers. Jean-Pierre Meyer Jack Morava W.
