- In
string theory, a
worldsheet is a two-dimensional
manifold which describes the
embedding of a
string in spacetime. The term was
coined by
Leonard Susskind...
- an
action of the two-dimensional
conformal field theory describing the
worldsheet of a
string in
string theory. It was
introduced by
Stanley Deser and Bruno...
- the
string means that only
interaction corresponding to an
orientable worldsheet are
allowed (e.g., two
strings can only
merge with
equal orientation)...
- dimensions. Both
theories are
based on
oriented closed strings. On the
worldsheet, they
differ only in the
choice of GSO projection. They were
first discovered...
-
through spacetime, a
string sweeps out a two-dimensional
surface called its
worldsheet. This is
analogous to the one-dimensional
worldline traced out by a point...
- to the
worldsheet curvature of
other strings, so
their abundance through space-time
determines the
measure by
which an
average string worldsheet will be...
-
closed strings. In addition,
depending on the
method used to fix the
worldsheet diffeomorphisms and
conformal transformations in the
original free string...
- of
possible vertex operators in the
worldsheet conformal field theory (CFT)—usually
those with
specific worldsheet fermion number and
periodicity conditions...
-
metric with
signature (−, +, +, +, ...), σ are the
coordinates for the
worldsheet of the
black p-brane, u is its four-velocity, r is the
radial coordinate...
-
relevant in
string theory where the two-dimensional
manifold is
named worldsheet.
Appreciation of its
generalized renormalizability was
provided by Daniel...
