Abstract
We construct a geometric realization of the Khovanov.Lauda.Rouquier algebra R associated with a symmetric Borcherds.Cartan matrix A = (a ij)i,j⋯ I via quiver varieties. As an application, if a ii ≠ = 0 for any i ⋯ I, we prove that there exists a one-to-one correspondence between Kashiwara's lower global basis (or Lusztig's canonical basis) of U-A (g) (respectively, V A(λ) and the set of isomorphism classes of indecomposable projective graded modules over R (respectively, Rλ).
