Young Stellar System Caught in Act of Forming Close Multiples
Young Stellar System Caught Forming Close Multiples
2016/11/4
For the first time, astronomers have seen a dusty disk of material around a young star fragmenting into a multiple-star system. Scientists had suspected such a process, caused by gravitational instabi...
Estimating Industry Multiples
Management Analysis Tools and Techniques Performance Mathematical Methods
2015/5/13
We analyze industry multiples for the S&P 500 in 1995. We use Gibbs sampling to estimate simultaneously the error specification and small sample minimum variance multiples for 22 industries. In additi...
Fast Computation of Common Left Multiples of Linear Ordinary Differential Operators
Algorithms complexity linear differential operators common left multiples
2013/9/3
We study tight bounds and fast algorithms for LCLMs of several linear differential operators with polynomial coefficients. We analyse the arithmetic complexity of existing algorithms for LCLMs, as wel...
Power multiples in binary recurrence sequences: an approach by congruences
Power multiples binary recurrence sequences approach by congruences
2010/12/13
We introduce an elementary congruence-based procedure to look for q-th power multiples in arbitrary binary recurrence sequences (q 3). The procedure allows to prove that no such multiples exist in m...
Thue-Morse at Multiples of an Integer
Thue-Morse sequence sum of digits congruences arithmetic progressions
2010/12/14
Let t = (tn)n0 be the classical Thue-Morse sequence defined
by tn = s2(n) mod 2, where s2 is the sum of the bits in the binary repre-sentation of n. It is well known that for any integer k ≥ 1 the f...
Finding Low Weight Polynomial Multiples Using Lattices
stream ciphers analysis low weight polynomial multiple lattices
2008/6/25
The low weight polynomial multiple problem arises in the context of stream ciphers ccryptanalysis and of efficient finite field arithmetic ,and is believed to be difficult.
Expectations on Mean-Reverting Profitability: Case of Valuation Multiples
Profitability Expectations Mean-reversion Valuation Multiples
2010/10/20
Despite the fact that corporate profits are mean-reverting (according to Fama by 38% a year) and even despite knowledge about this phenomenon is available for more than half a century, investors seem ...
