Acta Mathematica, 2005 A distinguished variety is a variety that exits the bidisk through the distinguished boundary. We show that Ando's inequality for commuting matrix contractions can be sharpened to looking at the maximum modulus on a distinguished variety, not the whole bidisk.

Minimal noncommutative varieties and power varieties [PDF]
Pacific Journal of Mathematics, 1984 A variety of finite monoids is a class of finite monoids closed under taking submonoids, quotients and \textit{finite} direct products. A language L is a subset of a finitely generated free monoid. The variety theorem of Eilenberg sets up a one to one correspondence between varieties of finite monoids and classes of languages called, appropriately ...

Most secant varieties of tangential varieties to Veronese varieties are nondefective
, 2015 We prove a conjecture stated by Catalisano, Geramita, and Gimigliano in 2002, which claims that the secant varieties of tangential varieties to the $d$th Veronese embedding of the projective $n$-space $\mathbb{P}^n$ have the expected dimension, modulo a ...

, 2017 Smooth Schubert varieties in rational homogeneous manifolds of Picard number 1 are horospherical varieties. We characterize standard embeddings of smooth Schubert varieties in rational homogeneous manifolds of Picard number 1 by means of varieties of ...

Variations in agronomic and grain quality traits of rice grown under irrigated lowland conditions in West Africa [PDF]
, 2018 Rice breeding in West Africa has been largely skewed toward yield enhancement and stress tolerance. This has led to the variable grain quality of locally produced rice in the region.

Geographical and Ecological Differences in Pepper Cultivation and Consumption in China
Frontiers in Nutrition, 2021 Peppers (Capsicum spp.) are used as food items, and particularly condiments, across most of the world. Accordingly, these vegetables occupy the largest annual stable planting area (>21,000 km2) in China.

Gromov-Witten invariants of a class of toric varieties [PDF]
, 2000 We describe the quantum cohomology rings of a class of toric varieties. The description includes, in addition to the (already known) ring presentations, the (new) analogues for toric varieties of the sorts of quantum Giambelli formulas which exist ...

Secant varieties of adjoint varietie
Matemática Contemporânea, 1998 The adjoint varieties of this paper are certain varieties obtained from the adjoint representation of a connected simple algebraic group -- they have nothing to do with the adjoints of classical algebraic geometry. It is shown that these adjoint varieties provide examples of varieties with degenerate secant varieties. The main results of the paper are:
