ON TWO FINITENESS CONDITIONS FOR HOPF ALGEBRAS WITH NONZERO INTEGRAL
(Scuola normale superiore di Pisa, 2015-06)
A Hopf algebra is co-Frobenius when it has a nonzero integral. It
is proved that the composition length of the indecomposable injective comodules over a co-Frobenius Hopf algebra is bounded. As a consequence, the coradical ...
Molecular dynamics computer simulation of scratch resistance testing of polymers: visualization
(Springer-Verlag, 2013-02)
Experimental scratch resistance testing provides two numbers: the penetration depth Rp and the healing depth Rh. In molecular dynamics computer simulations, we create a material consisting of N statistical chain segments ...
Flat-top oscillons in an expanding universe
(American Physical Society, 2010-04)
Oscillons are extremely long lived, oscillatory, spatially localized field configurations that arise from generic initial conditions in a large number of nonlinear field theories. With an eye towards their cosmological ...
Boundary terms and three-point functions: an AdS/CFT puzzle resolved
(Springer Nature, 2017-06)
N= 8 superconformal field theories, such as the ABJM theory at Chern-Simons level k = 1 or 2, contain 35 scalar operators O I J with Δ = 1 in the 35 v representation of SO(8). The 3-point correlation function of these ...
Coloring intersection graphs of x-monotone curves in the plane
(Springer-Verlag, 2014-06)
A class of graphs G is χ-bounded if the chromatic number of the graphs in G is bounded by some function of their clique number. We show that the class of intersection graphs of simple families of x-monotone curves in the ...
Extended Formulations for Polygons
(Springer-Verlag, 2012-03)
The extension complexity of a polytope P is the smallest integer k such that P is the projection of a polytope Q with k facets. We study the extension complexity of n-gons in the plane. First, we give a new proof that the ...
Valid Orderings of Real Hyperplane Arrangements
(Springer US, 2015-04)
Given a real finite hyperplane arrangement A and a point p not on any of the hyperplanes, we define an arrangement vo(A,p), called the valid order arrangement, whose regions correspond to the different orders in which a ...
Sample-optimal tomography of quantum states
(Association for Computing Machinery, 2016-06)
It is a fundamental problem to decide how many copies of an unknown mixed quantum state are necessary and sufficient to determine the state. This is the quantum analogue of the problem of estimating a probability distribution ...
Refined global Gan–Gross–Prasad conjecture for Bessel periods
(Walter de Gruyter, 2014-04)
We formulate a refined version of the global Gan-Gross-Prasad conjecture for general Bessel models, extending the work of Ichino-Ikeda and R. N. Harris in the co-rank 1 case. It is an explicit formula relating the automorphic ...
Unipotent representations as a categorical centre
(American Mathematical Society (AMS), 2015-10)
Let G(F[subscript q]) be the group of rational points of a split connected reductive group G over the finite field F[subscript q]. In this paper we show that the category of representations of G(F[subscript q]) which are ...
