In
mathematical objectivity, a
string (or
1-brane, or, more formally - a
1-dimensional object occupying some
metric space) is an arbitrarily one-dimensional (
1d)
curvilinear path integral (integrand) with (at most) two (
2)
endpoints (in/
input and out/
output)
called nuts.
Strings may be
open๐ or
closed๐, but not both. (see also
brane,
SMALL brane,
loopstring,
string ludology,
thread,
walk)
Computationally, a
string is a
stream (sequence) of
preimages (ie. a concatenation of
flageolet pencils).
