Universality of Gaussian-Mixture Reverse Kernels in Conditional Diffusion
Nafiz Ishtiaque, Syed Arefinul Haque, Kazi Ashraful Alam +1
We prove that conditional diffusion models whose reverse kernels are finite Gaussian mixtures with ReLU-network logits can approximate suitably regular target distributions arbitra…
Symmetry topological field theory and non-abelian Kramers-Wannier dualities of generalised Ising models
Clement Delcamp, Nafiz Ishtiaque
For a class of two-dimensional Euclidean lattice field theories admitting topological lines encoded into a spherical fusion category, we explore aspects of their realisations as bo…
Refined Invariants and Quantum Curves from Supersymmetric Localization
Sibasish Banerjee, Nafiz Ishtiaque, Saebyeok Jeong
We study an Aganagic-Vafa brane supported on a special Lagrangian submanifold in a non-compact toric Calabi-Yau threefold . From the perspective of geome…
R-matrices and Miura operators in 5d Chern-Simons theory
Nafiz Ishtiaque, Saebyeok Jeong, Yehao Zhou
We derive Miura operators for - and -algebras from first principles as the expectation value of the intersection between a topological line defect and a holomorphic surface d…
Elliptic Stable Envelopes for Certain Non-Symplectic Varieties and Dynamical -Matrices for Superspin Chains from the Bethe/Gauge Correspondence
Nafiz Ishtiaque, Seyed Faroogh Moosavian, Yehao Zhou
We generalize Aganagic-Okounkov's theory of elliptic stable envelopes, and its physical realization in Dedushenko-Nekrasov's and Bullimore-Zhang's works, to certain varieties witho…
