Abstract In this paper, we study generalized symmetric Finsler spaces. We first study symmetry preserving diffeomorphisms, then we show that the group of symmetry preserving diffeomorphisms is a transitive Lie transformation group. Finally we give some existence theorems. MSC: 53C60, 53C30
Keywords: Homogeneous finsler space, generalized symmetric finsler space, symmetry preserving diffeomorphism

Abstract Let â„•0 be the set of all non-negative integers and đ?’Ť(â„•0 ) be its the power set. An integer additive set-indexer (IASI) is defined as an injective function đ?‘“: đ?‘‰(đ??ş) → đ?’Ť(â„•0 ) such that the induced function đ?‘“ + : đ??¸(đ??ş) → đ?’Ť(â„•0 ) defined by đ?‘“ + (đ?‘˘đ?‘Ł) = đ?‘“(đ?‘˘) + đ?‘“(đ?‘Ł) is also injective, where đ?‘“(đ?‘˘) + đ?‘“(đ?‘Ł) is the sum set of đ?‘“(đ?‘˘) and đ?‘“(đ?‘Ł). If đ?‘“ + (đ?‘˘đ?‘Ł) = đ?‘˜ ∀ đ?‘˘đ?‘Ł ∈ đ??¸(đ??ş), then đ?‘“ is said to be a đ?‘˜-uniform integer additive set-indexer. An integer additive set-indexer đ?‘“ is said to be a weak integer additive set-indexer if |đ?‘“ + (đ?‘˘đ?‘Ł)| = đ?‘šđ?‘Žđ?‘Ľ ( |đ?‘“(đ?‘˘)|, |đ?‘“(đ?‘Ł)|) ∀ đ?‘˘đ?‘Ł ∈ đ??¸(đ??ş). We have some characteristics of the graphs which admit weak integer additive set-indexers. In this paper, we study about the sparing number of the corona of two graphs. Keywords: Integer additive set-indexers, mono-indexed elements of a graph, weak integer additive set-indexers, sparing number of a graph

On Some Triple Almost Lacunary Sequence Spaces Defined by Orlicz Functions Ayhan Esi* Department of Mathematics, University of Adiyaman, Turkey Abstract In this paper we introduce the concept of almost lacunary strong convergent triple sequences with respect to an Orlicz function and examine some properties of these sequence spaces. We also introduce and study almost lacunary statistical convergence for triple sequences and also present some inclusion relations.
Keywords: Preliminaries, real numbers, Pringsheim, nondecreasing

On the Riemann Hypothesis in The Light of The Littlewood Criterion of Equivalence Lukasz Andrzej Glinka* Science Editor, BSc Physics. Full Member at the American Association of International Researchers, American Institute for Policy Development, New York Abstract In 1859, Riemann extended the Euler study onto the case of a complex variable according to then new Cauchy's complex analysis. According to his point of view, all non-trivial zeros of the Riemann zeta function are located on the critical line s=1/2+it, where t is a real number. In 1912, Littlewood presented the equivalence criterion for the Riemann Hypothesis based on the Mertens function. In this paper, the Riemann Hypothesis is discussed and this is shown that the Littlewood criterion can be immediately applied for proving the Riemann Hypothesis, according to the analytic number theory.
Keywords: Analytic number theory, Riemann zeta function, rie-mann hypothesis, Littlewood criterion, Mellin transforms, Mertens function

Origin of Modern Mathematical Numeral – 0, 1, 2, 3, 4, 5, 6, 7, 8, 9: the Hindu-Indian-Brahmagubta, The Islamo-Arabic or the West? Auwalu Musa* Mubi North Education Authority, Mubi North Local Government Area, Adamawa State – Nigeria Abstract The aim of this paper is to examine, analyze and ascertain the root of the modern mathematical numeral system between the Indian-Hindu Brahmagubta, Islamo-Arabic and the Western numeral systems. The paper utilized secondary source of data. The methodology adopted by the paper is content analysis. The findings of the paper revealed that the origin of the shapes of our ten modern numerals do not concern the Indian mathematics history, as Hindus do not have full-fledged mathematical numeral system before the development of Arabic Numerals between 8th-15th Centuries. The character of Hindu-Indian numerals in whatever form and categories it belongs- Brahmagubta or anyone else, does not have any genealogical affiliations to the present modern mathematical numeral versions, as well the same thing applies to the Western mathematical systems. The paper argued that, the root/origin of the modern Arabic numeral is traced to its original and independent Arabic character versions, which transmuted from one stage to another with some state of galvanization - from Abjadi, Mashriki to Ghubari. The paper argued that apart from the non-reliability of the thesis of disparity in characters or shapes of the Arabic numerals compare to that of the HinduIndian Brahmagubta, there is also that of philosophical caricature fiction of genealogical linkage as well as the phonological misplacement of language or terms. The paper also argued that during the Golden-Age of Islam between 7th and 15th centuries, European arithmeticians especially in the eleventh, twelfth and part of thirteenth centuries, knew nothing about Arabic numerals; it was incredibly absent, they knew only the use of antiquated Roman numerals and Abacus in counting. In that regard, the Arabic numeral symbols (or system) were developed by Islamo-Arabic mathematicians, learned by Indians and some Europeans who cares about knowledge. In the east, the numeral system attracted the Indian mathematicians, while in Europe, the numeral system was first employed in Italy, then later France for practical purposes after the translation of the work of Al-Khwarizmi Mohammed Ibn Musa (Latin Algorithm) in 12th century into Latin by Gerard of Cremona, also known as Leonardo Fibonacci.
Keywords: Abjadi, Europe, Ghubari, Hindu-Indian-Brahmagubta, mathematics, islamo-Arabic-Numeral, Origin, Science, West.
