Knot polynomial invariants in classical Abelian Chern-Simons field theory

open access: yes, 2010
Kauffman knot polynomial invariants are discovered in classical abelian Chern-Simons field theory. A topological invariant $t^{I\left( \mathcal{L} \right) }$ is constructed for a link $\mathcal{L}$, where $I$ is the abelian Chern-Simons action and $t$ a ...

Grothendieck inequalities characterize converses to the polynomial method [PDF]

open access: yesQuantum
A surprising 'converse to the polynomial method' of Aaronson et al. (CCC'16) shows that any bounded quadratic polynomial can be computed exactly in expectation by a 1-query algorithm up to a universal multiplicative factor related to the famous ...

Polynomial Solutions of Equivariant Polynomial Abel Differential Equations

open access: yesAdvanced Nonlinear Studies, 2018
Let a⁢(x){a(x)} be non-constant and let bj⁢(x){b_{j}(x)}, for j=0,1,2,3{j=0,1,2,3}, be real or complex polynomials in the variable x. Then the real or complex equivariant polynomial Abel differential equation a⁢(x)⁢y˙=b1⁢(x)⁢y+b3⁢(x)⁢y3{a(x)\dot{y}=b_{1}(

Logarithmic corrected Polynomial $f(R)$ inflation mimicking a cosmological constant

open access: yes, 2016
In this paper, we consider an inflationary model of $f(R)$ gravity with polynomial form plus logarithmic term. We calculate some cosmological parameters and compare our results with the Plank 2015 data.

Theoretical and experimental results on time-series representations of polynomials

open access: yesFrontiers in Signal Processing
This study considers time-series representations of polynomials. Often in data modelling and many other applications, accurate estimations of the degree of a polynomial, of the noise standard deviation, and of the coefficient of the highest degree of a ...

Complexity of coalition structure generation [PDF]

open access: yes, 2011
We revisit the coalition structure generation problem in which the goal is to partition the players into exhaustive and disjoint coalitions so as to maximize the social welfare.

Hydrodynamics-based functional forms of activity metabolism: a case for the power-law polynomial function in animal swimming energetics. [PDF]

open access: yesPLoS ONE, 2009
The first-degree power-law polynomial function is frequently used to describe activity metabolism for steady swimming animals. This function has been used in hydrodynamics-based metabolic studies to evaluate important parameters of energetic costs, such ...

On Correctness of Cauchy problem for a Polynomial Difference Operator with Constant Coefficients

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
The theory of linear difference equations is applied in various areas of ma\-the\-matics and in the one-dimensional case is quite established. For $n>1$, the situation is much more difficult and even for the constant coefficients a general description of

Dispersion relation for water waves with non-constant vorticity

open access: yes, 2012
We derive the dispersion relation for linearized small-amplitude gravity waves for various choices of non-constant vorticity. To the best of our knowledge, this relation is only known explicitly in the case of constant vorticity.
