The Non-Uniform Perebor Conjecture for Time-Bounded Kolmogorov Complexity is False.
Electron. Colloquium Comput. Complex., 2023 The Perebor (Russian for "brute-force search") conjectures, which date back to the 1950s and 1960s are some of the oldest conjectures in complexity theory. The conjectures are a stronger form of the NP ≠ P conjecture (which they predate) and state that for "meta-complexity" problems, such as the Time-bounded Kolmogorov complexity Problem, and the ...

-openness of non-uniform hyperbolic diffeomorphisms with bounded -norm [PDF]
Ergodic Theory and Dynamical Systems, 2019 We study the $C^{1}$-topological properties of the subset of non-uniform hyperbolic diffeomorphisms in a certain class of $C^{2}$ partially hyperbolic symplectic systems which have bounded $C^{2}$ distance to the identity. In this set, we prove the stability of non-uniform hyperbolicity as a function of the diffeomorphism and the measure, and the ...

Properties of Water Bound in Hydrogels
Gels, 2017 In this review, the importance of water in hydrogel (HG) properties and structure is analyzed. A variety of methods such as 1H NMR (nuclear magnetic resonance), DSC (differential scanning calorimetry), XRD (X-ray powder diffraction), dielectric ...

Lower Bounds for the Constants in Non-Uniform Estimates of the Rate of Convergence in the CLT [PDF]
Journal of Mathematical Sciences, 2020 We conduct a comparative analysis of the constants in the Nagaev-Bikelis and Bikelis-Petrov inequalities which establish non-uniform estimates of the rate of convergence in the central limit theorem for sums of independent random variables possessing finite absolute moments of order $2+δ$ with $δ\in[0,1]$.

On an improved computational solution for the 3D HCIR PDE in finance
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019 The aim of this work is to tackle the three–dimensional (3D) Heston– Cox–Ingersoll–Ross (HCIR) time–dependent partial differential equation (PDE) computationally by employing a non–uniform discretization and gathering the finite difference (FD) weighting

Polynomial splines of non-uniform degree on triangulations: Combinatorial bounds on the dimension
Computer Aided Geometric Design, 2019 The authors study the dimension of the space of splines (or piecewise polynomial functions) defined on triangulations of a planar domain such that the maximum degree of the polynomial pieces differs across the distinct triangles of the partition. This type of splines are called \textit{non-uniform degree splines}. The approach used in the paper follows

Uniform approximation for period-quadrupling bifurcations. [PDF]
, 1998 . We derive a uniform approximation for semiclassical contributions of periodic orbits to the spectral density which is valid for generic period-quadrupling bifurcations in systems with a mixed phase space.
