The compatible Grassmannian [PDF]
Let A be a positive injective operator in a Hilbert space (H,〈{dot operator},{dot operator}〉), and denote by [ {dot operator}, {dot operator} ] the inner product defined by A: [f, g] = 〈A f, g〉.

Geometric Properties of Grassmannian Frames for
Grassmannian frames are frames satisfying a min-max correlation criterion. We translate a geometrically intuitive approach for two- and three-dimensional Euclidean space ( and ) into a new analytic method which is used to classify many Grassmannian ...

The automorphism group of the quantum grassmannian [PDF]
The automorphism group of a quantised coordinate algebra is usually much smaller than that of its classical counterpart. Nevertheless, these automorphism groups are often very difficult to calculate.

Grassmannian and String Theory [PDF]
Infinite-dimensional Grassmannian manifold contains moduli spaces of Riemann surfaces of all genera. This well known fact leads to a conjecture that non-perturbative string theory can be formulated in terms of Grassmannian. We present new facts supporting this hypothesis.

On the Sato-Segal-Wilson Grassmannian and the infinite Grassmannian of type I+,-
In this thesis, we present the Sato-Segal-Wilson Grassmannian and its dual, the infinite Grassmannian of type I+,−. We provide detailed proofs that they are infinite dimensional complex manifolds and Hermitian symmetric spaces. By doing so, we tie up some

On Derived Categories of Generalized Grassmannian Flips
In this paper, we construct and classify a new family of flips, called generalized Grassmannian flips, by generalizing the construction of standard flips for $\mathbb{P}^m\times \mathbb{P}^n$ to any generalized Grassmannian $G/P$, where $P$ is a maximal ...

Grassmannian and flag sigma models on interval: phase structure and L-dependence
We discuss the two-dimensional Grassmannian SU(N)/S(U(N − 2) × U(2)) and the flag SU(N )/S(U(N − 2) × U(1) × U(1)) sigma models on a finite interval and construct analytical solutions of gap equations in the large-N limit.

Graßmannian integrals in Minkowski signature, amplitudes, and integrability
We attempt to systematically derive tree-level scattering amplitudes in fourdimensional, planar, maximally supersymmetric Yang-Mills theory from integrability.

Linear embeddings of grassmannians and ind-grassmannians
By a grassmannian we understand a usual complex grassmannian or possibly an orthogonal or symplectic grassmannian. We classify, with few exceptions, linear embeddings of grassmannians into larger grassmannians, where the linearity requirement is the condition that the embedding induces an isomorphism on Picard groups.
