the editorial
note,
"Einstein
on
Gravitation and
Relativity:
The
Collaboration with Marcel
Grossmann,"
pp.
294-301,
for
a
historical discussion.
In
a
letter
from
1915
Einstein claimed that Grossmann "did
not
contribute
substantially
to
the results"
("trug
aber materiell nichts
zu
den
Ergebnissen
bei." Einstein
to
Arnold
Sommerfeld,
15
July
1915).

the
physical
and
epistemological
reasons
to
include
non-
linear transformations in Einstein

for
more on
the role
that Mach's ideas
played
in
Einstein's
thinking.
[5]This is
a
version of the
equivalence principle,
which
was
first
formulated
by
Einstein
in
1907 (see
Einstein
1907j [Vol. 2,
Doc.
47],
§17).
It had
played
an
important
heuristic role
in
Einstein's search for
a
relativistic
theory
of
gravitation (see
Vol.
4,
the editorial
note,
"Einstein
on
Gravitation and
Relativity:
The Static
Field,"
pp.
122-128,
for
a
discussion).
See
also Ein-
stein

for further elucidation.
[6]"idt" should be "it."
[7]The
superscripts
a
should
be
subscripts.
[8]See
Ricci and Levi-Civita
1901.
[9]The
derivatives
should
be
partial
derivatives.
[10]"(2)"
should be
"(20)."
[11]Here and
in
the
equation
below the
subscript
"k" should
be
"k."
[12]The
superscript pairs
"tax,"
"Kß,"
"wß,"
and "Ka" should be
subscripts.
[13]"Faß"
should be
"Faß."
[14]"Linse"
should
be
"Linie."

that
equation

(23), (24), and (23a)

[19]"a-1"
should be

[20]There
should
be
a
minus
sign
between the
two
derivatives
in
the second
term
in
the
sec-
ond
summation.
[21]In
the
second and
third
terms
on
the
right-hand
side
a
summation
over
x
is
implied,
as
are
summations
over
a
and
x
in
the
following terms.
[22]A
summation
over a
is
implied.
[23]Following
Weyl,
V-tensors
were
later named "tensor densities"
("Tensordichten."
Weyl
1918b).
[24]See,
e.g.,
Laue
1911
for Max Laue's
formulation.
Einstein
had used Laue's
approach
ear-
lier
in
an
unpublished manuscript
on
the
special theory
of
relativity (see Vol.
4,
Doc.
1).
[25]"o
=
1" should be "a
=
2" and vice
versa.
[26]"(42)"
should
be "(42a)."
LIV
[27]In
eq.
(46)
"g"
should be
"g^v."
Earlier,
Einstein
had
denoted the
quantities
gmv as
the
components
of the
gravitational
field
(see
Einstein 1914e
[Vol. 4,
Doc.
25],
p. 177).
