AbstractAccording to current information the secrets of the universe can not be solved by using rational numbers because the irrational numbers have been used more than the rational numbers in the creation of universe but the real values of irrational numbers have not been known. The most excellent program of brain is written in left angular gyrus in right handed persons; but unfortunately the nural networks of angular gyrus do not have the understanding ability of irrational numbers so far. And even, angular gyrus lesions can cause the loss of normal mathematical ability that this phemonon is known as The Gerstmann’s Syndrome. Then, we hypothetised that it is impossible to destroy uncertainity problem unless irrational numbers are rationalised. If the neural networks of angular gyrus will more develop by evolution mechanisms, the irrationality problem would be solved in the future? Agulary gyruses analyzed a synoptically by clinical and experimental ways. We show that normal angular gyrus could not solve irrationality and the more developed neural networks of the angular gyrus could succed in the uncertainity problem solving by irrationality. Interestingly, the more clever wild cats have more mathematical ability than domestic cats because wild cats have more glial cells in their bigger angular gyruses than domestic cats. If so, has angular gyrus has not been thoroughly developed to understand irrational numbers? According to current theories, have all of us Gerstmann’s Syndrome?Keywords : Mathematics, Medical

AbstractThe aim of this research paper is to consider some P_s –Diophantine triples including integer numbers under the special condition for s=55. It is demonstrated that they can not be extended to P_55 –Diophantine quadruples but they are regular. Also, several properties on the elements of this type sets are obtained. Some notations such as Modular Arithmetic, Quadratic Reciprocity or Residue Law, Legendre Symbol are used to prove our results.Keywords : Diophantine mTuples, P_s Diophantine Triple, Quadratic Residue and Reciprocity Law, Legendre Symbol, Prime Factorization

AbstractIn this paper, we observe some new spaces to obtain new β and γ type duality of a sequence space λ, related to the some sequence spaces. Before this we give some new distinguished subspaces of an FK space obtained by an operator of Ayd n and Başar [2], which is stronger than common C1 Cesàro oper ator. We also give some structural theorems and inclusions for these distinguished subspaces. Finally we prove some theorems related to the f, ars and arb duality of a sequence space λ like Goes [14] and Buntinas [8]. These theorems are important to decade the duality of a sequence space in summability theory and topological sequence spaces theory.Keywords : FK spaces, Matrix methods, β, γ, f duality.

AbstractAnalytical solution of highly nonlinear system of two dimensional Volterra integral equations is studied by the reduced dierential transform method [RDTM]. We present a new property of RDTM to acquire the recursive relation which is used to get analytical solution of the above mentioned two dimensional system. Results of the nu merical examples obtained by RDTM are compared with the existing results obtained by TDDTM. Though solutions obtained by RDTM and TDDTM are same, RDTM has signicant advantage over TDDTM that is RDTM generates the solution of the nonlinear problem by operating the multivariable function with respect to a desired variable only not on all of their independent variables unlike in TDDTM so that RDTM reduces the time consumption than TDDTM.Keywords : Reduced dierential transform method, Volterra integral equa tions
