چکیده
In this work we study the differential aspects of noncommutative geometry for magnetic $C^*$-algebra which is a 2-cocycle deformation group $\mathbb{R}^2$. This algebra intimately related to Quantum Hall Effect in continuous, and our results aim provide new geometric interpretation Kubo's formula. Taking inspiration from ideas developed by Bellissard during 80's, build an appropriate Fredholm module based on Dirac operator square root (\`a la Dirac) quantum harmonic oscillator. Our main result consist establishing important piece Bellissard's theory, so-called second Connes' order do so, establish equality three cyclic 2-cocycles defined dense subalgebra $C^*$-algebra. Two these are literature quantized calculus, with use Dixmier trace operator.

Hamiltonian Gravity and Noncommutative Geometry
A version of foliated spacetime is constructed in which the spatial geometry is described as a time dependent noncommutative geometry. The ADM version of the gravitational action is expressed in terms of these variables. It is shown that the vector constraint is obtained without the need for an extraneous shift vector in the action.
متن کاملSome Aspects of Noncommutative Geometry and Physics
An introduction is given to some selected aspects of noncommutative geometry. Simple examples in this context are provided by finite sets and lattices. As an application, it is explained how the nonlinear Toda lattice and a discrete time version of it can be understood as generalized σ-models based on noncommutative geometries. In particular, in this way one achieves a simple understanding of t...
متن کاملNoncommutative Differential Geometry of Generalized Weyl Algebras
Elements of noncommutative differential geometry of Z-graded generalized Weyl algebras A(p; q) over the ring of polynomials in two variables and their zero-degree subalgebras B(p; q), which themselves are generalized Weyl algebras over the ring of polynomials in one variable, are discussed. In particular, three classes of skew derivations of A(p; q) are constructed, and three-dimensional first-...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
