Hilbert series of the finite dimensional generalized Heckealgebras

Quantum mechanics in finite dimensional Hilbert space

The quantum mechanical formalism for position and momentum of a particle in a one dimensional cyclic lattice is constructively developed. Some mathematical features characteristic of the finite dimensional Hilbert space are compared with the infinite dimensional case. The construction of an unbiased basis for state determination is discussed.

The Hilbert Space of Quantum Gravity Is Locally Finite-Dimensional

We argue in a model-independent way that the Hilbert space of quantum gravity is locally finite-dimensional. In other words, the density operator describing the state corresponding to a small region of space, when such a notion makes sense, is defined on a finite-dimensional factor of a larger Hilbert space. Because quantum gravity potentially describes superpositions of different geometries, i...

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Finite-Dimensional Hilbert Space and The Linear Inverse Problem

Linear Vector Space. A Vector Space, X , is a collection of vectors, x ∈ X , over a field, F , of scalars. Any two vectors x, y ∈ X can be added to form x+y ∈ X where the operation “+” of vector addition is associative and commutative. The vector space X must contain an additive identity (the zero vector 0) and, for every vector x, an additive inverse −x. The required properties of vector addit...
