Construction of instantons
WebSep 1, 2016 · The ADHM construction reveals the Kähler quotient structure of the instanton moduli space and provides the scheme to calculate the non-perturbative corrections in the path integral. It is natural to generalize the instantons in four dimensions to higher and lower dimensions. WebThe hyper-Kahler quotient construction of instantons on an ALE space is a natural generalization of the ADHM construction of instantons on R4. It is also natural in terms of D-branes [2], and has served, again, as an important example in string theory. Recently [8], a brane construction has been used to describe an analog of the ADHM

Duality conditions WebIn Section 2 we introduce the ADHM-like construction of unitary instantons on CP 2, reviewing as well some relevant aspects of the standard ADHM construction of instantons on C 2, introducing in particular several spaces which will play a role in later sections. We then embed the ADHM-like construction into a gauge theory admitting
WebIn the ADHM construction of instantons, one looks for zero-modes of the Dirac-like operator. The feature peculiar to the noncommutative case is that these zero-modes project out some states in the Fock space. The mechanism of these projections is clarified in the case that the gauge group is U (1). WebInstantons in gauge theories: solutions of Euclidean equations of motion.
