http://hdl.handle.net/10525/3464
Title: Notes on Lattice Ordered Aalgebras<br/><br/>Authors: Yılmaz, Ruşen<br/><br/>Abstract: In this paper we introduce a new class of lattice ordered algebra, which will be called a pseudo-almost f-algebra; namely, a lattice ordered algebra A in which a ∧ b = 0 in A implies ab ∧ ba = 0. We present somefundamental properties of pseudo-almost f-algebras and consider their relationships with various type of lattice ordered algebras; mainely, f-algebras, almost f-algebras and d-algebras. 2010 Mathematics Subject Classification: Primary 46A40, 46B42; Secondary 06F25, 13J25.Wed, 01 Jan 2014 00:00:00 GMTStrong Converse Result for Baskakov Operator

Title: Empirical Bayes Two-Sided Test for the Parameter of Linear Exponential Distribution for Random Index<br/><br/>Authors: Juan, Huang<br/><br/>Abstract: In the case of random index, the empirical Bayes two-side test rule for the parameter of linear exponential distribution is constructed. The asymptotically optimal property for the proposed EB test is obtained under suitable conditions. It is shown that the convergence rates of the proposed EB test rules can arbitrarily close to O(n^−1/2). 2010 Mathematics Subject Classification: 62C12, 62F15.Wed, 01 Jan 2014 00:00:00 GMTEssential Norms of Weighted Composition Operators on L^1 Müntz Spaces
http://hdl.handle.net/10525/3461
Title: Essential Norms of Weighted Composition Operators on L^1 Müntz Spaces<br/><br/>Authors: Al Alam, Ihab; Lefèvre, Pascal<br/><br/>Abstract: This paper discusses the problem of boundedness and compactness for weighted composition operators defined on a Müntz subspace of L^1([0,1]). We compute the essential norm of such operators when the symbol ϕ of the composition operator satisfies a special condition (condition (β)). As a corollary, we obtain the exact values of essential norms of composition and multiplication operators. This completes the corresponding results of the first named author in the framework of Müntz subspaces of C([0, 1]). 2010 Mathematics Subject Classification: 47B33, 47B38.Wed, 01 Jan 2014 00:00:00 GMTOn Lie Algebras with Exponential Growth of the Codimensions

Title: On Lie Algebras with Exponential Growth of the Codimensions<br/><br/>Authors: Bogdanchuk, O. A.; Mishchenko, S. P.; Verëvkin, A. B.<br/><br/>Abstract: We study the asymptotic behaviour of the codimension sequence of varieties of Lie algebras variety over a field of characteristic zero. We construct an infinite series of such varieties with different fractional exponents. This extends the special cases known before. 2010 Mathematics Subject Classification: 17B01, 16R10, 16P90.Wed, 01 Jan 2014 00:00:00 GMTSubordinated Markov Branching Processes and Lévy Processes
http://hdl.handle.net/10525/3459
Title: Subordinated Markov Branching Processes and Lévy Processes<br/><br/>Authors: Mayster, Penka<br/><br/>Abstract: We consider the jump structure of the subordinated Lévy processes and subordinated Markov branching processes. Subordination provides a method of constructing a large subclass of Markov or Lévy processes Y (t) = X(T (t)), where X(t) is a Markov or Lévy process and T (t) is a continuous time subordinator independent of X(t); that is a Lévy process with positive increments and T (0) = 0. Let X(t) be a Lévy process. Then subordination preserves the independence and stationarity of the increments, but it changes their amplitudes and the total mass of the Lévy measure. Let X(t) be a Markov branching process. Then subordination (owing to the independence of X(t) and T (t)) preserves the Markov property, but it disturbs the branching property. The infinitesimal generator of the subordinated process Y (t) involves the total progeny of reproduction. The intensity of the jump times depends on the subordinator’s Bernstein function. 2010 Mathematics Subject Classification: 60J80, 60K05.<br/><br/>Description: [Mayster Penka; Майстер Пенка]Wed, 01 Jan 2014 00:00:00 GMTAvailability of a Repairable k-out-of-n: G System with Repair Times Arbitrarily Distributed

Title: Availability of a Repairable k-out-of-n: G System with Repair Times Arbitrarily Distributed<br/><br/>Authors: Gherda, Mebrouk; Boushaba, Mahmoud<br/><br/>Abstract: An k-out-of-n: G system is a system that consists of n components and works if and only if k components among the n work simultaneously. The system and each of its components can be in only one of two states: working or failed. When a component fails it is put under repair and the other components stay in the “working” state with adjusted rates of failure. After repair, a component works as new and its actual lifetime is the same as initially. If the failed component is repaired before another component fails, the (n − 1) components recover their initial lifetime. The lifetime and time of repair are independent. In this paper, we propose a technique to calculate the mean time of repair, the probability of various states of the system and its availability by using the theory of distribution. 2010 Mathematics Subject Classification: 90B25, 60K10.Wed, 01 Jan 2014 00:00:00 GMTNew Oscillation Criteria for Third Order Nonlinear Neutral Delay Difference Equations with Distributed Deviating Arguments

Title: Schur-Szegö Composition of Small Degree Polynomials<br/><br/>Authors: Kostov, Vladimir Petrov<br/><br/>Abstract: We consider real polynomials in one variable without root at 0 and without multiple roots. Given the numbers of the positive, negative and complex roots of two such polynomials, what can be these numbers for their composition of Schur-Szegö? We give the exhaustive answer to the question for degree 2, 3 and 4 polynomials and also in the case when the degree is arbitrary, the composed polynomials being with all roots real, and one of the polynomials having all roots but one of the same sign. 2010 Mathematics Subject Classification: 12D10.<br/><br/>Description: [Kostov Vladimir Petrov; Костов Владимир Петров]Wed, 01 Jan 2014 00:00:00 GMTLimit of Three-Point Green Functions: the Degenerate Case

Title: Limit of Three-Point Green Functions: the Degenerate Case<br/><br/>Authors: Quang Hai, Duong; Thomas, Pascal J.<br/><br/>Abstract: We investigate the limits of the ideals of holomorphic functions vanishing on three points in C^2 when all three points tend to the origin, and what happens to the associated pluricomplex Green functions. This is a continuation of the work of Magnusson, Rashkovskii, Sigurdsson and Thomas, where those questions were settled in a generic case. 2010 Mathematics Subject Classification: 32U35, 32A27.Wed, 01 Jan 2014 00:00:00 GMTMost General Fractional Representation Formula for Functions and Implications

Title: Most General Fractional Representation Formula for Functions and Implications<br/><br/>Authors: Anastassiou, George A.<br/><br/>Abstract: Here we present the most general fractional representation formulae for a function in terms of the most general fractional integral operators due to S. Kalla, [3], [4], [5]. The last include most of the well-known fractional integrals such as of Riemann-Liouville, Erdélyi-Kober and Saigo, etc. Based on these we derive very general fractional Ostrowski type inequalities. 2010 Mathematics Subject Classification: 26A33, 26D10, 26D15.Wed, 01 Jan 2014 00:00:00 GMTEmpirical Bayes Test for the Parameter of Exponential-Weibull Distribution under Negative Associated Samples
