Product Description
Lefschetz's Topology was written in the period in between the beginning of topology, by Poincare, and the establishment of algebraic topology as a well-formed subject, separate from point-set or geometric topology. At this time, Lefschetz had already proved his first fixed-point theorems. In some sense, the present book is a description of the broad subject of topology into which Lefschetz's theory of fixed points fits. Lefschetz takes the opportunity to describe some of the important applications of his theory, particularly in algebraic geometry, to problems such as counting intersections of algebraic varieties. He also gives applications to vector distributions, complex spaces, and Kronecker's characteristic theory. ... Read more

Not a bit user friendly
I bought this book because I want and need to know about this subject.
I have come to really dislike this book and this author, because
although some of the information I want is here, it is presented so badly, it is very hard work to get it. It is mathematics authorship like this that gives math a bad name.
This text was written in the '50's before the Deligne breakthroughs in this area and the later concentration on Calabi-Yau Algebraic varieties
in the area of mirror symmetry. He uses K for R ( real) and KP_n
for projective spaces, but mostly he is just sloppy about notation for sums and even vectors. His definitions always seem to leave me wondering what exactly he means. Mostly he leaves me wanting a book to explain his book. As a cheap starting place for Algebraic Geometry, you may want to pass this one up until you read something better? ... Read more

Case of the dog that didn't bark ?
If the autor happens to be the same person as the Solomon Lefschetz regarded as one of America's greatest mathematicians, it is difficult to
understand the apparent neglect by Amazon user's of his works listed on the Amazon website. Maybe he may not be pedantic enough for some of the
er, xcientiss in these days of complicating everything as much as possible,given the redundancy in so much of mathematics brought about by
the pocket calculator. I suppose we will have to chalk it all down as another one of life's little mysteries I suppose. ... Read more

Aus Wikipedia. Nicht dargestellt. Auszug: Fritz Heider (February 18, 1896 - January 2, 1988) was an Austrian psychologist whose work was related to the Gestalt school. In 1958 he published The Psychology of Interpersonal Relations, which systematized and expanded upon his creation of balance theory and attribution theory. Heider was born in Vienna, Austria in 1896. His approach to higher education was rather casual, and he wandered freely throughout Europe studying and traveling as he pleased for many years. At the age of 24 he received a Ph.D. from the University of Graz, for his innovative study of the causal structure of perception, and traveled to Berlin, where he worked at the Psychology Institute. In 1930, Heider was offered an opportunity to conduct research at the Clarke School for the Deaf in Northampton, Massachusetts, which was associated with Smith College, also in Northampton. This prospect was particularly attractive to him because Kurt Koffka, one of the founders of the Gestalt school of psychology, held a position at Smith College (Heider, 1983). It was in Northampton that he met his wife Grace (née Moore). Grace was one of the first people Heider met in the United States. As an assistant to Koffka, she helped Heider find an apartment in Northampton and introduced him to the environs (Heider, 1983). They were married in 1930, and the marriage lasted for more than 50 years, producing three sons: Karl, John, and Stephan (in birth order). Karl Heider went on to become an important contributor to visual anthropology and ethnographic film. John Heider wrote the popular "The Tao of Leadership." Heider published two importan...http://booksllc.net/?l=de ... Read more
