A five-variable counterexample to the Hessian conjecture, and the low-dimensional status of the Jacobian and Hessian conjectures
Guowu Meng, Liang Yang
We exhibit an explicit integer polynomial in five variables, of total degree and with constant Hessian determinant , whose gradient is not injective. Consequently its for…
On higher extensions of quiver representations over
Changjian Fu, Liang Yang, Zhiyuan Zeng
We show that higher extension spaces between finite-dimensional nilpotent -representations maybe infinite-dimensional, thereby clarifying a misconception in the liter…
Dirac series of
Yi-Hao Ding, Chao-Ping Dong, Chengyu Du +2
This paper classifies the Dirac series of , the linear quaternionic real form of complex . One tool for us is a further sharpening of the Helgason-Johnson bound in…
Dirac series for some real exceptional Lie groups
Jian Ding, Chao-Ping Dong, Liang Yang
Up to equivalence, this paper classifies all the irreducible unitary representations with non-zero Dirac cohomology for the following simple real exceptional Lie groups: ${\rm EI}=…
