چکیده

Positive geometries provide a modern approach for computing scattering amplitudes in variety of physical models. In order to facilitate the exploration these new geometric methods, we introduce Mathematica package called “amplituhedronBoundaries” calculating boundary structures three positive geometries: amplituhedron, momentum amplituhedron and hypersimplex. The first two are relevant planar N=4 supersymmetric Yang–Mills theory, while last one is well-studied polytope appearing many contexts mathematics, closely related m=2 amplituhedron. includes an array useful tools study geometries, including their stratifications, drawing posets, additional manipulating combinatorial Grassmannians.

The Amplituhedron

Perturbative scattering amplitudes in gauge theories have remarkable simplicity and hidden infinite dimensional symmetries that are completely obscured in the conventional formulation of field theory using Feynman diagrams. This suggests the existence of a new understanding for scattering amplitudes where locality and unitarity do not play a central role but are derived consequences from a diff...

determinant of the hankel matrix with binomial entries

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

Positive Amplitudes In The Amplituhedron

The all-loop integrand for scattering amplitudes in planar N = 4 SYM is determined by an “amplitude form” with logarithmic singularities on the boundary of the amplituhedron. In this note we provide strong evidence for a new striking property of the superamplitude, which we conjecture to be true to all loop orders: the amplitude form is positive when evaluated inside the amplituhedron. The stat...
