Ideals in BIT speciale varieties

open access: yes, 2021
Ideals in BIT speciale varieties are characterized. In particular, it is proved that, for any finitary BIT speciale variety, there is a finite set of ideal terms determining ideals. Several ideal term sets of this kind are given. For the variety of groups one of these sets consists of the terms $y_1y_2$, $xyx^{-1}$, $x^{-1}y^{-1}x$ (and $y$ which can ...

Representations on Hessenberg Varieties and Young's Rule [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
We combinatorially construct the complex cohomology (equivariant and ordinary) of a family of algebraic varieties called regular semisimple Hessenberg varieties. This construction is purely in terms of the Bruhat order on the symmetric group. From this a

Grothendieck ring class of Banana and Flower graphs

open access: yes, 2012
We define a special type of hypersurface varieties inside $\mathbb{P}_k^{n-1}$ arising from connected planar graphs and then find their equivalence classes inside the Gr\"othendieck ring of projective varieties. Then we find a characterization for graphs

STUDY OF NODULATION AND NITROGEN FIXATION IN ANNUAL SPECIES AND VARIETIES OF VETCHLING, GENUS LATHYRUS

open access: yesВавиловский журнал генетики и селекции, 2014
The number of root nodules and nitrogen fixation rate (judged from nitrogenase activity) have been studied in nine varieties of five annual vetchling species: Lathyrus sativus, L. tingitanus, L. chlorantus, L. ochrus, and L. odoratus.

Security of growing habits and bud formation of German sour cherry varieties

open access: yesInternational Journal of Horticultural Science, 2011
Intensive sour cherry production is concerned to find the most productive varieties under special growing conditions. High planting density, adapted to manual picking or on the other hand to mechanical harvesting.

The Expected Codimension of a Matroid Variety [PDF]

open access: yes, 2013
Matroid varieties are the closures in the Grassmannian of sets of points defined by specifying which Pl\"ucker coordinates vanish and which don't. In general these varieties are very ill-behaved, but in many cases one can estimate their codimension by ...

Special effect varieties in higher dimension

open access: yes, 2004
Here we introduce the concept of special effect varieties in higher dimension and we generalize to the n-dimensional projective space, n>=3, the two conjectures given in AG/0410527 for the planar case.
