Introduction to Cherkis bow varieties

Résumé : Cherkis bow varieties are found in the ADHM type description of instantons on the Taub-NUT space. They were originally given in terms of Nahm’s equations, but I will give their quiver description, which are useful for analysis of their properties, such as normality, description of symplectic leaves, local description at a singular
point, etc. If time permits, I will explain that bow varieties with the so-called balanced condition are Coulomb branches of quiver gauge theories of affine type A. This is a joint work with Yuuya Takayama.
