  2. Brane - Wikipedia

    en.wikipedia.org/wiki/Brane

    Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics. They have mass and can have other attributes such as charge . Mathematically, branes can be represented within categories , and are studied in pure mathematics for insight into homological mirror symmetry and noncommutative geometry .

  3. D-brane - Wikipedia

    en.wikipedia.org/wiki/D-brane

    The arrangement of D-branes constricts the types of string states which can exist in a system. For example, if we have two parallel D2-branes, we can easily imagine strings stretching from brane 1 to brane 2 or vice versa. (In most theories, strings are oriented objects: each one carries an "arrow" defining a direction along its length.) The ...

  4. M-theory - Wikipedia

    en.wikipedia.org/wiki/M-theory

    For example, a point particle can be viewed as a brane of dimension zero, while a string can be viewed as a brane of dimension one. It is also possible to consider higher-dimensional branes. In dimension p, these are called p-branes. Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics.

  5. M2-brane - Wikipedia

    en.wikipedia.org/wiki/M2-brane

    The M2-brane solution can be found [1] by requiring () symmetry of the solution and solving the supergravity equations of motion with the p-brane ansatz. The solution is given by a metric and three-form gauge field which, in isotropic coordinates, can be written as

  6. Mirror symmetry (string theory) - Wikipedia

    en.wikipedia.org/wiki/Mirror_symmetry_(string...

    The Calabi–Yau manifolds used in string theory are of interest in pure mathematics, and mirror symmetry allows mathematicians to solve problems in enumerative algebraic geometry, a branch of mathematics concerned with counting the numbers of solutions to geometric questions.

  7. M5-brane - Wikipedia

    en.wikipedia.org/wiki/M5-brane

    As such, it can be described explicitly as a black brane solution [1] to eleven-dimensional supergravity, the low-energy limit of M-theory. In particular, it carries a magnetic charge under the 3-form gauge field of the 11-dimensional supergravity multiplet. The M5-brane is the electric-magnetic dual of the M2-brane.

  8. Superstring theory - Wikipedia

    en.wikipedia.org/wiki/Superstring_theory

    Investigating theories of higher dimensions often involves looking at the 10 dimensional superstring theory and interpreting some of the more obscure results in terms of compactified dimensions. For example, D-branes are seen as compactified membranes from 11D M-theory. Theories of higher dimensions such as 12D F-theory and beyond produce other ...

  9. Topological string theory - Wikipedia

    en.wikipedia.org/wiki/Topological_string_theory

    The worldvolume theory on a stack of N D2-branes is the string field theory of the open strings of the A-model, which is a U(N) Chern–Simons theory. The fundamental topological strings may end on the D2-branes. While the embedding of a string depends only on the Kähler form, the embeddings of the branes depends entirely on the complex structure.
