These notes are based on the course of lectures I gave at Harvard in the fall of 1964. They constitute a self-contained account of vector bundles and K-theory assuming only the rudiments of point-set topology and linear algebra. One of the features of the treatment is that no use is made of ordinary homology or cohomology theory. In fact, rational cohomology is defined in terms of K-theory.The theory is taken as far as the solution of the Hopf invariant problem and a start is mode on the J-homomorphism. In addition to the lecture notes proper, two papers of mine published since 1964 have been reproduced at the end. The first, dealing with operations, is a natural supplement to the material in Chapter III. It provides an alternative approach to operations which is less slick but more fundamental than the Grothendieck method of Chapter III, and it relates operations and filtration. Actually, the lectures deal with compact spaces, not cell-complexes, and so the skeleton-filtration does not figure in the notes. The second paper provides a new approach to K-theory and so fills an obvious gap in the lecture notes.
Informally, $K$-theory is a tool for probing the structure of a mathematical object such as a ring or a topological space in terms of suitably parameterized vector spaces and producing important intrinsic invariants which are useful in the ...
9.2 The index map and partial isometries We give in this section another picture of the index map pointed out to us by George Elliott . Besides having a stronger flavor of " index ” , this picture is more intuitive and in most cases ...
Algebraic K-Theory
This book covers the connection between algebraic K-theory and Bökstedt, Hsiang and Madsen's topological cyclic homology and proves that the difference between the theories are ‘locally constant’.
It is a great satisfaction for a mathematician to witness the growth and expansion of a theory in which he has taken some part during its early years.
This handbook offers a compilation of techniques and results in K-theory. These two volumes consist of chapters, each of which is dedicated to a specific topic and is written by a leading expert.
From the Introduction: "These notes are taken from a course on algebraic K-theory [given] at the University of Chicago in 1967.
We will not treat applications in detail; however, we will outline the most striking of the applications to date in a section at the end, as well as mentioning others at suitable points in the text.
This is an introduction to algebraic K-theory with no prerequisite beyond a first semester of algebra (including Galois theory and modules over a principal ideal domain).
The answer (known as Bloch's formula, see [Quillen, Theorem 5.19 and Srinivas, Corollary 5.27) is that CH*(X) = H*(X, Kk, x), where K*,x is the sheaf given by “sheafifying” the presheaf U → Kk(U), for U a Zariski-open subset of X.
