Abstract We study the relationship of viscosity and weak solutions to equation $$\begin{aligned} \smash {\partial _{t}u-\varDelta _{p}u=f(Du)}, \end{aligned}$$ ? t u - ? <mm...

Continuing [6], [8] and [15], we study the consequences of the weak Freese-Nation property of (P(ω),⊆). Under this assumption, we prove that most of the known cardinal invariants including all of those appearing in Cichoń’s diagram take the same value as in the corresponding Cohen model. Using this principle we could also strengthen two results of W. Just about cardinal sequences of superatomic...

Vulnerabilities related to weak passwords are a pressing global economic and security issue. We report a novel, simple, and effective approach to address the weak password problem. Building upon chaotic dynamics, criticality at phase transitions, CAPTCHA recognition, and computational round-off errors we design an algorithm that strengthens security of passwords. The core idea of our simple met...

We study local-global questions for Galois cohomology over the function field of a curve defined over a p-adic field, the main focus being weak approximation of rational points. We construct a 9-term Poitou–Tate type exact sequence for tori over a field as above (and also a 12-term sequence for finite modules). Like in the number field case, part of the sequence can then be used to analyze the ...

We use quantum invariants to define a 3-manifold invariant jp which lies in the non-negative integers. We relate jp to the Heegard genus, and the cut number. We show that jp is an invariant of weak p-congruence.

Choice functions on tournaments always select the maximal element (Condorcet winner), provided they exist, but this property does not hold in the more general case of weak tournaments. In this paper we analyze the relationship between the usual choice functions and the set of maximal elements in weak tournaments. We introduce choice functions selecting maximal elements, whenever they exist. Mor...

We present the status and preliminary results of the analysis of kinematically fully reconstructed weak bosons at the STAR experiment. The transverse single-spin asymmetry (AN) has been measured in transversely polarized proton-proton collisions at √ s = 500 GeV, with a recorded integrated luminosity of 25 pb−1. The measured observable is sensitive to the non-universality of the Sivers function...
