Summary: Self-duality plays a crucial role in the study and application of topological solitons, leading to the development of exact methods and nonperturbative techniques. The paper presents a generalization of the Yang-Mills-Higgs system by introducing scalar fields in a symmetric and invertible matrix, maintaining conformal invariance in three-dimensional space. The model allows new scalar fields to adjust themselves to solve modified self-duality equations for various configurations of gauge and Higgs fields.

Summary: This paper investigates the multi-Regge limit of scattering amplitudes in strongly-coupled N = 4 super Yang-Mills and finds that the set of possible excitations appearing in analytic continuation is constrained. It also shows that the BFKL eigenvalue of any possible Reggeon bound state is a multiple of the eigenvalue in the six-gluon case.

Summary: We demonstrate the close relationship between the approaches to integrable systems using 4d Chern-Simons theory and symmetry reductions of the anti-self-dual Yang-Mills equations, at least in the classical case. By starting from holomorphic Chern-Simons theory on twistor space and performing symmetry reductions, we obtain theories for 2d integrable systems and 4d Chern-Simons theory with disorder defects. Additionally, a reduction by a single translation leads to a 5d partially holomorphic Chern-Simons theory describing the Bogomolny equations.

Summary: A universal formula for the Nicolai map using a coupling flow functional differential operator has been found recently. The full perturbative expansion of this operator in Yang-Mills theories with off-shell supersymmetry is presented, allowing for the computation of the explicit Nicolai map to any order in the gauge coupling. This work extends the previously known construction method to arbitrary gauges and from the gauge hypersurface to the full gauge-field configuration space.

Summary: We propose a conjecture for the three-point functions of single-trace operators in planar N=4 super-Yang-Mills theory at finite coupling, specifically when two operators are protected. Our proposal is based on the hexagon representation for structure constants of long operators, which we extend to incorporate operators of arbitrary length using data from the TBA-QSC formalism. We perform various tests of our conjecture, finding agreement with the gauge theory through 5 loops for the shortest three-point function and with string theory in the classical limit.

Summary: In this study, we investigate the exact WKB method for the quantum Seiberg-Witten curve of 4d N = 2 pure SU(3) Yang-Mills in the language of abelianization. We explore the relevant differential equation, its solutions, and associated Stokes phenomena using the exact WKB method. Additionally, we investigate the exact quantization condition for a specific spectral problem. Our analysis also leads us to consider new Darboux coordinates on a moduli space of flat SL(3,C)-connections and numerical analysis supports the conjecture that these coordinates have asymptotic expansions given by the formal quantum periods series.

Summary: In the study, a cusped Wilson line with J insertions of scalar fields in N = 4 SYM was considered, showing that in a certain limit the Feynman diagrams are integrable at all loop orders. The integrable system was identified as a quantum fishchain with open boundary conditions. The derivation of the Baxter equation for Q-functions and quantization condition for the spectrum allowed for numerical determination of the non-perturbative spectrum.

Summary: In this study, we calculate the corrections to the coupling constant in the long-distance effective theory of center-stabilized SU(N) Yang-Mills theories on R3 x S1, and show that the results align with previous studies. Additionally, our findings provide an intuitive interpretation of the coupling constant running in the context of the nonperturbative emergent latticized fourth dimension.

Summary: The study shows that in the trace deformed Yang-Mills theory, the glueball mass remains consistent with its value at zero temperature when center symmetry is restored, and is not significantly affected by the compactification radius. Additionally, a connection between the deformation parameter and effective compactification size has been established.

Summary: The inverse Penrose transform for self-dual Yang-Mills and its higher-spin extensions is presented on a flat background. The twistor action for the higher-spin extension of SDYM is of BT-type, and a new action describing a higher-spin extension of Yang-Mills theory is discovered through a deformation away from the self-dual sector of HS-SDYM. The twistor action for HS-YM is a straightforward generalization of the Yang-Mills one.

Summary: In this study, we consider a static black hole immersed in the Power-Yang-Mills field in four-dimensional Einstein-Gauss-Bonnet gravity and investigate the effects of various parameters on the radius of the photon sphere. We use a modified form of the Newman-Janis algorithm to obtain a rotating black hole solution in this gravity. Furthermore, we explore the influence of the Yang-Mills magnetic charge Q with power q, Gauss-Bonnet parameter alpha, and spin a on the horizon radius. It is observed that all the parameters have a significant effect on the shadow and related physical observables. The constraint values for the spin, magnetic charge, and Gauss-Bonnet parameters are obtained using the shadow size of supermassive black holes from the EHT observations.

Summary: This paper explores the limits of N = 4 super-Yang-Mills theory that approach BPS bounds. The resulting non-relativistic theories, known as Spin Matrix Theories, describe the effective dynamics near the BPS bounds and are obtained by reducing N = 4 SYM on a three-sphere and integrating out non-dynamical fields. Previous works have studied various subsectors in this limit, and this paper constructs the remaining Spin Matrix Theories near the 1/8-BPS subsectors. Hamiltonians are derived using the spherical reduction algorithm and shown to match the results from loop corrections. In the PSU(1,1 | 2) case, the positivity of the spectrum is proven by constructing cubic supercharges and their closure to the interacting Hamiltonian. The symmetry structure of the sectors is also analyzed.

Summary: The study focuses on limits of N = 4 super-Yang-Mills theory approaching BPS bounds, leading to non-relativistic near-BPS theories known as Spin Matrix theories. By reducing N = 4 SYM on a three-sphere and integrating out certain fields, the near-BPS theories can be obtained. The near-BPS limit with SU(1, 2|2) symmetry shows new features, including a dynamical gauge field, which differs from previous cases with SU(1) symmetry.
