Is toric duality a Seiberg-like duality in (2+1)-d ? [PDF]

, 2014
We show that not all $(2+1)$ dimensional toric phases are Seiberg-like duals. Particularly, we work out superconformal indices for the toric phases of Fanos ${\cal{C}}_3$, ${\cal{C}}_5$ and ${\cal{B}}_2$. We find that the indices for the two toric phases

Near visual function measured with a novel tablet application in patients with astigmatism

Clinical and Experimental Optometry, EarlyView., 2020
Clinical relevance While the clinical focus of performance metrics is traditionally based on visual acuity, research from the field of visual impairment has demonstrated that metrics such as reading speed and critical print size correlate much more strongly with subjective patient reported outcomes and assessed ability in real‐world tasks.

Toric difference variety [PDF]

Journal of Systems Science and Complexity, 2017
In this paper, the concept of toric difference varieties is defined and four equivalent descriptions for toric difference varieties are presented in terms of difference rational parametrization, difference coordinate rings, toric difference ideals, and group actions by difference tori.

Toric Hilbert schemes

Duke Mathematical Journal, 2002
The classical Hilbert scheme introduced by \textit{A. Grothendieck} [Sém. Bourbaki 1960/1961, Exp. 221 (1961; Zbl 0236.14003)], parametrizes subschemes of \(\mathbb P^r_k, k\) a field, with a given Hilbert polynomial. A toric variety is a variety parametrized by a finite number of monomials \({\mathbf t}^{a_i} = t_1^{a_1}\cdots t_d^{a_d}, i = 1,\ldots ...
