Quantum mechanics,strong emergence and ontological non-reducibility
Interpretation of quantum mechanics emergence downward causation
2016/6/13
We show that a new interpretation of quantum mechanics, in which the notion of event is defined without reference to measurement or observers, allows to construct a quantum ontology based on systems, ...
Ideal-Cipher (Ir)reducibility for Blockcipher-Based Hash Functions
Hash function Blockcipher
2014/3/12
Preneel et al.~(Crypto 1993) assessed 64 possible ways to construct a compression function out of a blockcipher. They conjectured that 12 out of these 64 so-called PGV constructions achieve optimal se...
Random Self-Reducibility Properties of Learning Problems over Burnside Groups of Exponent 3
foundations / Random self-reducibility Learning with errors Post-quantum cryptography Non-commutative cryptography Burnside groups
2012/3/27
In this work we investigate the hardness of a computational problem introduced in the recent work of Baumslag et al. In particular, we study the $B_n$-LHN problem, which is a generalized version of th...
Reducibility of cocycles under a Brjuno-Russmann arithmetical condition
Brjuno-Russmann arithmetical condition Dynamical Systems
2011/9/19
Abstract: The arithmetics of the frequency and of the rotation number play a fun- damental role in the study of reducibility of analytic quasi-periodic cocycles which are sufficiently close to a const...
A Computational Complexity-Theoretic Elaboration of Weak Truth-Table Reducibility
algorithmic information theory algorithmic randomness weak truth-table reducibility
2011/9/14
Abstract: The notion of weak truth-table reducibility plays an important role in recursion theory. In this paper, we introduce an elaboration of this notion, where a computable bound on the use functi...

Let G be a connected reductive algebraic group defined over an algebraically closed field of positive characteristic. We study a generalization of the notion of G-complete reducibility in the context ...

2010/11/24
Let $G=G(K)$ be a simple algebraic group defined over an algebraically closed field $K$ of characteristic $p>0$. A subgroup $X$ of $G$ is said to be $G$-completely reducible if, whenever it is contai...
Almost reducibility for finitely differentiable SL(2,R)-valued quasi-periodic cocycles
reducibility finitely differentiable SL(2,R)-valued quasi-periodic cocycles
2010/11/12
Quasi-periodic cocycles with a diophantine frequency and with values in SL(2,R) are shown to be almost reducible as long as they are close enough to a constant, in the topology of k times differentia...

Let $G$ be a connected reductive algebraic group defined over an algebraically closed field %$k$ of characteristic $p > 0$. Our first aim in this note is to give concise and uniform proofs for two fu...
Resonance equals reducibility for A-hypergeometric systems
toric hypergeometric Euler–Koszul homology D-module resonant
2010/12/8
Classical Theorems of Gel’fand et al., and recent results of Beuk-ers show essentially that non-confluent A-hypergeometric systems have re-ducible monodromy representation if and only if the continuou...
Development of a Spectrophotometric Assay System for Evaluating Reducibility of Water-Soluble Substances

2009/6/18
A spectrophotometric assay system for evaluating reducibility of water-soluble substances using native bovine oxymyoglobin (MbO2) was developed. With incubation of MbO2 solution at fixed temperature a...
