Re: ELEMENTARY REFERENCES FOR MATHEMATICAL INDUCTION

This post corrects one typo in the (first) version
that I posted yesterday. In David Fowler's paper [24],
"<<Modern number _it_ a symbol>>" is corrected to "<<Modern
number _is_ a symbol>>". The correct phrase appears in my
LaTex document. Apparently, while removing/replacing the
LaTex code \textit{is}, which renders "is" in italicized
form, to a usenet version of italicization, namely "_is_",
I must have accidentally deleted the "s" at one point. Then,
a few seconds later, when I realized that I had deleted
one of the characters that shouldn't have been "backspaced
over", I must have retyped a "t" in its place by mistake.
Incidentally, I've doubled checked with the original papers,
and "is", as I now have it, appears in both Fowler's [24]
paper and in Unguru's [63] paper. (The phrase in question
was actually a phrase that Fowler was quoting from Unguru's
paper. Moreover, in both Fowler's rendering of the quote
and in the original version that was in Unguru's paper,
"is" is italicized. The doublearrow notation "<<...>>"
appears in the papers, by the way, and is not a form of
ASCII adjustment to the original text.)
A discussion of mathematical induction came up in another
math list that I participate in, and it occurred to me
that it would be a good idea to archive (in sci.math)
a list of some elementary references for mathematical
induction that I've had in a LaTex document for several
years.

complete induction?", Archive for History of Exact
Sciences 55 (2000), 5776.
(from pp. 5758) It is a generally accepted opinion
that the first instance of _conscious_use_ of Complete
Induction (henceforth CI) as a proof method is contained
in the "Traité du triangle arithmétique" by Blaise PASCAL
(16231662) [...] A very different question is to establish
whether, before PASCAL, convincing examples of _use_ of CI
as a proof technique are attested, disconnected from the
perception of the fact that it happened to be a particular
instance of a general demonstrative scheme. Scholars have
found proofs fitting in the scheme of CI in almost every
geographical ambit of prePascalian mathematics. Some of
these proposals, especially those concerning the ancient
mathematical corpus, are untenable, even surprising in
view of the serious misunderstandings they contain. Recently,
the polemical tone of the debate has attained a local
maximum: in FOWLER 1994 _versus_ UNGURU 1994 preconceptions
of historiographical method have strongly influenced the
evaluation of the relevant instance of CI. In this sense,
both FOWLER's and UNGURU's analyses, though interesting in
several respects, seem to me to have missed their target.
Moreover, a careful survey of the literature shows that
every single scholar sets up his own reading of the principle
of CI, and on this basis he is able to affirm or to deny that
specific proofs constitute well formed examples of it. My
aim is to increase the confusion on this subject. In fact,
I suggest to regard a PLATONIC passage, i.e. "Parmenides"
149a7c3, as a fullfledged example of proof by CI.

(From p. 254) For Unguru, the symbolic form of [mathematical
induction] is an essential feature of its use. This allows
him to fit it in his general approach which starts, on the
one hand, from his uncontentious observation that there is
no sign of such symbolic manipulation in Greek mathematics,
and, on the other, from his attitude to modern mathematics
which can be encapsulated in his assertion: <<Modern number
_is_ a symbol>> (p. 282). Given such an approach, Unguru
has no difficulty in establishing that it would be
impossible for the Greeks to have employed _his_kind_ of
mathematical induction [...] I prefer a less formal approach
to mathematical induction, which I will characterise here
by a loose translation from the French of Pascal's own
description [...]

(From pp. 237238) The name _mathematical_induction_ is
apparently due to DE MORGAN (1838) [Cajori above is
footnoted]. As for the use of recursion in formal proofs,
BLAISE PASCAL (16231662) has been credited with the
invention of this technique. Thus FLORIAN CAJORI [review
in Bull. Amer. Math. Soc. 15 (190809), 405408], although
he found evidence for "recurrent processes" in CAMPANUS
(1260) and even earlier in PROCLUS (410485), concluded
that these are "not exactly induction which is best ascribed
to Pascal". However, shortly thereafter, G. VACCA [see Vacca,
below] claimed the discovery of the principle of mathematical
induction for FRANCESCO MAUROLICO (14941575), and this
view remained unchallenged until recently when the entire
subject was examined anew by Professor HANS FREUDENTHAL
[MR 14,1049h; Zbl 50.24202]. He carefully reviewed
MAUROLICO'S work and found only two or at best three
instances of a very primitive kind of induction. [A footnote
mentions that Bussey (above) is more generous in his
evaluation of Maurolico.] Dr. FREUDENTHAL examines also
older sources and in passing, he refers to a report that
"Lewi ben Gerson (12881344) im Sefer Maasei Choscheb soll
die Anzahl n! der Permutationen von n Elementen mit Induktion
berechnet haben." However he does not investigate this
source, and concludes that PASCAL was indeed the first one
to formulate the Principle of Induction. Earlier authors
used proofs that were not really general, since they worked
with specific numbers. However, where the proof can readily
be applied to arbitrary n, FREUDENTHAL calls it
"quasigeneral", but, while the use of such a proof can
properly be considered an application of mathematical
induction, its users can hardly be credited with the general
principle. A closer look at the work of R. LEVI BEN GERSHON,
in his _Maasei_Hoshev_, will show that he is in fact the
earliest writer known to have used induction systematically
in all generality and to have recognized it as a distinct
mathematical procedure.

We will prove by mathematical induction that all positive
integers are odd, using only the obvious lemma that when
N is odd, N + 2 is also odd. Let P(N) denote the proposition
"All of the integers 1, 2, 3, ..., N are odd."
Step 1: P(1) obviously.
Step 2: Assume P(k). Then by definition 1, 2, 3, ..., k
are all odd. In particular k  1 is odd. Then k  1 + 2,
that is, k + 1 is also odd. Thus, 1, 2, 3, ... k, k + 1
are all odd, or P(k + 1). This completes the induction.

(Author's Summary) The article examines the alleged
instances of mathematical induction in Greek mathematics
showing them to be actually noninductive. Furthermore
the author argues for the historical _impossibility_ of
the existence of genuine inductive proofs within the
confines of Greek mathematics. The article ends with
some general considerations on the nature of the history
of mathematics as a _historical_ discipline, meant to
set the specific analysis of the cited examples into
the broader methodological context of possible approaches
to the history of mathematics.

(From p. 268) How can Fowler both agree with two of my
most substantive conclusions and yet disagree with my
article? By adopting a laxer interpretive viewpoint than
mine, a viewpoint, moreover, in which the guiding light
is mathematical, rather than contextual, narrowhistorical,
intentional, voluntaristic, hermeneutical. To put it
bluntly, Fowler brings to the texts a willingness, which
I lack, to overinterpret them, a readiness to read into
the texts <<obvious>> mathematical implications which,
I think, are lacking and which he easily discerns with
his keen mathematical eye, as lying just below the surface
and bubbling up, bursting forth obtrusively, begging to
be acknowledged by the seer.
