Functional lower bounds for arithmetic circuits and connections to boolean circuit complexity [PDF]
, 2016 We say that a circuit $C$ over a field $F$ functionally computes an $n$-variate polynomial $P$ if for every $x \in \{0,1\}^n$ we have that $C(x) = P(x)$. This is in contrast to syntactically computing $P$, when $C \equiv P$ as formal polynomials. In this

On Existence and Uniqueness to Homogeneous Boltzmann Flows of Monatomic Gas Mixtures [PDF]
Archive for Rational Mechanics and Analysis, 2018 We solve the Cauchy problem for the full non-linear homogeneous Boltzmann system of equations describing multi-component monatomic gas mixtures for binary interactions in three dimensions.

Left-Inverses of Fractional Laplacian and Sparse Stochastic Processes [PDF]
, 2010 The fractional Laplacian $(-\triangle)^{\gamma/2}$ commutes with the primary coordination transformations in the Euclidean space $\RR^d$: dilation, translation and rotation, and has tight link to splines, fractals and stable Levy processes.

From the Birkhoff-Gustavson normalization to the Bertrand-Darboux integrability condition
, 2000 The Bertrand-Darboux integrability condition for a certain class of perturbed harmonic oscillators is studied from the viewpoint of the Birkhoff-Gustavson(BG)-normalization: By solving an inverse problem of the BG-normalization on computer algebra, it is

Maier-Saupe nematogenic fluid: field theoretical approach
Condensed Matter Physics, 2011 We adopt a field theoretical approach to study the structure and thermodynamics of a homogeneous Maier-Saupe nematogenic fluid interacting with anisotropic Yukawa potential.

Tachyon Condensation in a Chromomagnetic Center Vortex Background
UniverseThe chromomagnetic vacuum of SU(2) gluodynamics is considered in the background of a finite radius flux tube (center vortex) with a homogeneous field inside and a zero field outside. In this background, there are tachyonic modes.

, 2008 The gravitational collapse of a wide class of self-interacting homogeneous scalar fields models is analyzed. The class is characterized by certain general conditions on the scalar field potential, which, in particular, include both asymptotically ...
