as a possible avenue towards the quantization of general relativity. This is<br />
one of the main streams to attack this outstanding problem in mathematical physics,<br />
although one has to recognize that it has had less impact than string and superstring<br />
theories.</p>
<p>Before starting to read the book, I was delighted to have in my hands what<br />
it seemed to be a leisurely introduction to a topic of such novelty, in<br />
which my background as differential geometer and (mathematical) gauge<br />
theorist could be well suited. The first chapters give overall<br />
introductions in differential geometry, general relativity, semi-riemannian<br />
geometry, always keeping an informal style. So informal that at some points<br />
in touches the incorrectness. However, when reading these chapters, some of<br />
the times even skipping parts (so basic for a mathematician), this was<br />
to be forgiven. Around the second third of the book, physical<br />
(and more interesting) ideas enter the discussion (Yang-Mills theories, quantum mechanics,<br />
quantum field theory), and then the book swaps to the usual "physics<br />
jargon", so extraneous to a mathematician. No much<br />
intention not to lose people not already familiar with the theory<br />
is shown in the text, accompanied by a lack of motivation when introducing physical concepts.<br />
Moreover, not even for the experts the material is<br />
going to be of much use, since details are skipped once and again. The third<br />
part of the book (loop general relativity, loop quantum cosmology) is basically<br />
a review of very technical material. This is where the book touches the topic<br />
announced in the title, but by then all arguments follow a physics line of<br />
reasoning: no rigorous proofs, renormalizations, divergences, etc.<br />
Again, I have gone through a text in mathematical<br />
physics on which my expectations have not been fulfilled. Maybe next time.</p>
