We construct the world-volume action of a probe D3-brane in AdS_5×S^5 with
N units of flux. It has the field content, symmetries, and dualities of the U(1)
factor of N = 4 U(N + 1) super Yang–Mills theory, spontaneously broken to
U(N)×U(1) by being on the Coulomb branch, with the massive fields integrated
out. This motivates the conjecture that it is the exact effective action, called a
highly effective action (HEA). We construct an SL(2,ℤ) multiplet of BPS soliton
solutions of the D3-brane theory (the conjectured HEA) and show that they
reproduce the electrically charged massive states that have been integrated out
as well as magnetic monopoles and dyons. Their charges are uniformly spread
on a spherical surface, called a soliton bubble, which is interpreted as a phase
boundary.https://authors.library.caltech.edu/records/g6bfj-pba30Diffeomorphism Symmetry in Two Dimensions and Celestial Holography

Two-dimensional diffeomorphism symmetry can be described by an operator
algebra extension of the well-known Virasoro algebra description of conformal
symmetry. Utilizing this extension, this note explains why the conformal
symmetry that appears in celestial holography should not be extended to
diffeomorphism symmetry, a possibility that several authors have proposed. The
description of the two-dimensional diffeomorphism algebra presented here might
be useful for other purposes.https://authors.library.caltech.edu/records/d2bej-72m20
