# Talk:Ising model: exact results

Reviewer A

The next remarkable discovery was made in 1952 : is there a
reason not to mention that Onsager in 1948 wrote the exact value
of the spontaneous magnetization (without proof!) (I mean
Kaufman, B., Onsager, L.: Comment to the ``theory of regular
solutions* following the paper by G.S. Rushbrooke, Supplemento*
Nuovo Cimento, {\bf6}, 261, 1949.) Also as far as I know the
great paper of Yang does not find the spontaneous magnetization
because it computes the limit quoted ($H\to 0^+$) by studying it
in a field which tends to zero in the thermodynamic limit:
obtaining in principle a quantity $\le$ than the spontaneous
magnetization (defined by the limit in the present article: whose
actual identity with the limit and validity of the Onsager and
Yang magnetization was found quite later (if I am not mistaken):
maybe the Author can enlighten the reader on the matter.

spontane.eous in line 1 of "Spin Correlation Functions"

Determinental Representation : should it be Determinantal ??

Aside from the above minor remarks I find the article very informative and useful: the recent progress in the exact derivation of various scaling laws make the present review even more important as an easily accessible tool for reference to the major features of the Ising model, written by one of its main contributors.

It would be very helpful if where to find each item (or formula), presented in the article, was linked to one of the appended references, possibly indicating even the page. This could be done very easily by the Author who could indicate to the editors the appropriate information (for insertion in the text).
