On K-Stability of Reductive Varieties
Valery Alexeev, Ludmil Katzarkov
G. Tian and S.K. Donaldson formulated a conjecture relating GIT stability of a polarized algebraic variety to the existence of a Kahler metric of constant scalar curvature. In [Don…
Effective cones of quotients of moduli spaces of stable n-pointed curves of genus zero
William F. Rulla
Let X_n := \bar M_{0,n}, the moduli space of n-pointed stable genus zero curves, and let X_{n,m} be the quotient of X_n by the action of the symmetric group S_{n-m} on the last n-m…
State complexes for metamorphic robots
A. Abrams, R. Ghrist
A metamorphic robotic system is an aggregate of homogeneous robot units which can individually and selectively locomote in such a way as to change the global shape of the system. W…
Scalar and vector form factors of the in-medium nucleon
K. Saito, K. Tsushima
Using the quark-meson coupling model, we calculate the form factors at sigma- and omega-nucleon strong-interaction vertices in nuclear matter. The Peierls-Yoccoz projection techniq…
Bound Nucleon Form Factors, Quark-Hadron Duality, and Nuclear EMC Effect
K. Tsushima, D. H. Lu, W. Melnitchouk +2
We discuss the electromagnetic form factors, axial form factors, and structure functions of a bound nucleon in the quark-meson coupling (QMC) model. Free space nucleon form factors…
Moduli of affine schemes with reductive group action
Valery Alexeev, Michel Brion
For a connected reductive group G and a finite-dimensional G-module V, we study the invariant Hilbert scheme that parameterizes closed G-stable subschemes of V affording a fixed, m…
