Secant varieties of Grassmann varieties [PDF]
Proceedings of the American Mathematical Society, 2004 In this paper we discuss the dimensions of the (higher) secant varieties to the Grassmann varieties, embedded via the Plucker embeddings. We use Terracini's Lemma and the duality in the exterior algebra of a finite dimensional vector space to translate the problem into that of finding the dimension of a graded piece of a " fat" ideal in the exterior ...

Experimental Mathematics, 2017 In this paper we will prove that the six-dimensional Göpel variety in $P^{134}$ is generated by 120 linear, 35 cubic and 35 quartic relations. This result was already obtained in [RS] , but the authors used a statement in [Co] saying that the Göpel variety set theoretically is generated by the linear and cubic relations alone.

Is Every Toric Variety an M-variety? [PDF]
manuscripta mathematica, 2006 A complex algebraic variety X defined over the real numbers is called an M-variety if the sum of its Betti numbers (for homology with closed supports and coefficients in Z/2) coincides with the corresponding sum for the real part of X. It has been known for a long time that any nonsingular complete toric variety is an M-variety.

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 ...
