Combinatorics of Vogan diagrams for almost-Kähler manifolds
Alice Gatti
Let be a non-compact classical semisimple Lie group and let be the adjoint orbit with respect to a fixed element in . These manifolds can be equipped with an almost-Kä…

Graph Partitioning and Sparse Matrix Ordering using Reinforcement Learning and Graph Neural Networks
Alice Gatti, Zhixiong Hu, Tess Smidt +2
We present a novel method for graph partitioning, based on reinforcement learning and graph convolutional neural networks. Our approach is to recursively partition coarser represen…

Almost Kaehler geometry of adjoint orbits of semisimple Lie groups
Alberto Della Vedova, Alice Gatti
We study the almost Kaehler geometry of adjoint orbits of non-compact real semisimple Lie groups endowed with the Kirillov-Kostant-Souriau symplectic form and a canonically defined…
