ON THE SUM AND MAXIMAL TERM OF TAYLOR-DIRICHLET TYPE SERIES

PRECARPATHIAN BULLETIN OF THE SHEVCHENKO SCIENTIFIC SOCIETY Number
The article deals with Taylor-Dirichlet type series of the form $F(x)=\sum\nolimits_{k=0}^{+\infty}a_ke^{x\lambda_k+\tau(x)\beta_k},$ where $(\lambda_k)$ and $(\beta_k)$ are some sequence of non-negative numbers, and$\tau(x)$ is a non-negative non ...

Maximal predictability under long-term mean reversion

Journal of Empirical Finance, 2017
Abstract I analyse the relationship between two stylized empirical facts for stock returns: Unconditional long-term mean reversion and predictability by variables such as the dividend-price ratio or the short-term interest rate. In particular, I show that if one imposes that returns satisfy long-term mean reversion, this implies an upper bound on the

Maximization of long-term productivity in a rat colony

Laboratory Animals, 1972
Maximization of intensive breeding in the animal colony can be approached using a simple mathematical treatment of the production-time curve. It has been found that in a colony of specified-pathogen-free albino rats whose breeding dams were averaging litters of 11 at 6-week intervals, the stock should be entirely replaced at intervals of 27-28 weeks ...

Maximizing Short-Term Stock Prices through Advertising

SSRN Electronic Journal, 2010
This paper provides evidence that managers use firm advertising, in part, to maximize short-term stock prices. First, this paper shows that increased advertising spending is associated with individual investors' intensified buying activities, as well as a contemporaneous rise in abnormal stock returns that is subsequently reversed.

Nonlinear boundary value problems with maximal monotone terms

Aequationes Mathematicae, 2000
The authors consider a second-order nonlinear differential equation with maximal monotone terms and nonlinear, possibly multivalued boundary conditions. Using the theory of maximal monotone operators and the Leray-Schauder alternative the authors establish the existence of solutions.

Short‐Term Energy Maximization of Egret Foraging

Ecology, 1979
min = 0.1X and 'the inequality becomes: 4.8 kJ/ min X > 0.313 kJ/min 0.X or X < 4.99 kJ/min. Therefore it should rob if the cost of robbing is less than 4.99 kJ/min. While the actual foraging costs are not available, they can be approximated using a form of Kleiber's (1975) metabolic equation: metabolic rate (MR) = kW75f.

Which I.I.D. Sums are recurrently dominated by their maximal terms?

Journal of Theoretical Probability, 1993
Let \((X_ n)_{n\geq 1}\) be i.i.d. random variables with common distribution function \(F\) and \(P(X_ 1\neq 0)>0\). Put \(S_ n=\sum^ n_{i=1} X_ i\), \(S^*_ 0=0\), \(S^*_ n=\sup_{1\leq i\leq n}| S_ i|\), \(n\geq 1\). The authors characterize \(\limsup_{n\to\infty} (X_ n/S^*_{n-1})=\infty\) a.s. in terms of the distribution function \(F\).

Study of a Maximal Monotone Model with a Delay Term

SIAM Journal on Numerical Analysis, 2003
We present a model involving a friction term and a delay term. By using results of existence and uniqueness for maximal monotone differential inclusions, we give theoretical results for this model. An implicit Euler numerical scheme and results related to order of convergence are also provided from both a theoretical and a numerical point of view.
