The iCoulomb branch and shifted iYangian conjecture

Let $Q=({\mathbb I},\Omega)$ be an ADE quiver, let $(V_i;W_i)_{i\in{\mathbb I}}$ be a representation of its framed double quiver, and impose the stated Satake-diagram symmetry and parity conditions on $V$ and $W$. Let $\mathcal M_C^\imath(V^\imath,W^\imath)$ be the associated iCoulomb branch and ${}^\imath\overline{\mathcal{W}}_\mu^\lambda$ the corresponding affine Grassmannian islice. The iCoulomb branch and shifted iYangian conjecture. The iCoulomb branch $\mathcal M_C^\imath(V^\imath,W^\imath)$ is a normalization of a top-dimensional component of ${}^\imath\overline{\mathcal{W}}_\mu^\lambda$, and truncated shifted iYangians are subalgebras of quantized Coulomb branches. The statement is presented as a new conjectural relationship between iCoulomb branches, affine Grassmannian islices, and shifted iYangians; the paper gives no resolution.
