• A COMBINED SDLINAR(p) MODEL AND IDENTIFICATION AND PREDICTION OF ITS
LATENT COMPONENTS

• Authors: Miodrag Srboljub Djordjevic
Pages: 919 - 946
Abstract: The main subject of this paper is a combined integer-valued autoregressive time series with both positive and negative values, based on a new thinning operator. Some important properties are analyzed. Estimators of the unknown parameters are derived and their asymptotic behavior are analyzed. A simulation and an
application on real-data are, also, shown. At the end, a mechanism for identification and prediction of latent dimensions of the model are presented.

• Soft connected properties and irresolute soft functions based on b-open
soft sets

• Authors: Alaa Mohamed Abd El-latif
Pages: 947 - 967
Abstract: In this paper, we introduce another application on the b-open soft sets [10], by
studying the notion of connectedness based on it. We gave the basic denitions and
theorems about it. Further, we introduce the notion of b-irresolute soft functions as a
generalization to the b-continuous soft functions and study their properties in detail.
Finally, we show that, the surjective b-irresolute soft image of soft b-connected space
is also soft b-connected.

• FIXED POINT THEOREMS FOR TWO PAIRS OF MAPPINGS IN PARTIAL METRIC SPACES

• Authors: Valeriu POPA, Alina-Mihaela PATRICIU
Pages: 969 - 980
Abstract: In this paper a general fixed point theorem for two pairs of weakly compatible mappings satisfying a \phi - implicit relation different than the type from [14] is proved. As applications, we obtain the sufficient conditions for the existence of fixed
points for a sequence of mappings in partial metric spaces.

OPERATORS IN HILBERT SPACES

• On maximal function and V-conjugation

Pages: 999 - 1009
Abstract: We proved that on the 3-series field H1
cannot be defined by means of the V-conjugation. In other words, the norms kf k
H1 and k~f k L1 are not equivalent. This answers the question formulated in [12]. Also, we prove that the mean value of the function on the coset IN 1(x) is dominated by maximal operator, either by MN 1 or MN on some translated element.

functions focusing their relative type and relative weak type

• h-exponential change of Finsler metric

• Authors: Manish Kumar Gupta, Anil K. Gupta
Pages: 1029 - 1039
Abstract: In this paper, we studied a Finsler space whose metric is given by an \textsl{h}-exponential change and obtain the Cartan connection coefficients for the change. We also find the necesssary and sufficient condition for an h-exponential change of Finsler metric to be projective.

• ON THE BASE SPACE OF AN ALMOST PARACONTACT SUBMERSION

• Authors: Tshikunguila Tshikuna-Matamba
Pages: 1041 - 1049
Abstract: The purpose of this note is to describe the base space of an almost paracontact submersion. Here the base space is an almost para-Hermitian manifold. So, the paper intertwines paracontact and para-Hermitian structures via the theory of submersions.

• ON GENERALIZED M-PROJECTIVE -RECURRENT TRANS-SASAKIAN MANIFOLDS

• Authors: Jai Prakash Jaiswal, Arjun Singh Yadav
Pages: 1051 - 1060
Abstract: The aim of the present paper is to study generalized M-projective phi-recurrent trans-Sasakian manifold and its various geometric properties. First, we nd the sucient condition for generalized M-projective phi-recurrent trans-Sasakian manifold to become Einstein. Then non-existence of generalized M-projective phi-recurrent
trans-Sasakian manifold has been shown under some certain conditions.
At the last, the sucient condition for super generalized Ricci-recurrent
was also established.

equations of Kirchhoff type with density in $\mathbb{R}^{n}$

• Authors: Abbes Benaissa, Abderrahmane Beniani, Khaled Zennir
Pages: 1073 - 1090
Abstract: System of viscoelastic wave equations of Kirchhoff type isconsidered. For wider class of relaxation functions, we use a spaces weighted by density function to establish a very general decay rate of solution.

• SUPRA HOMEOMORPHISM IN SUPRA TOPOLOGICAL ORDERED SPACES

• Authors: Mohamed Abo-elhamayel, Tareq M. Al-shami
Pages: 1091 - 1106
Abstract: The purpose of this paper is to introduce the concepts of x-supra continuous (open, closed,homeomorphism) maps in supra topological ordered spaces for x  in {I,D,B}. We study the relationship among these types with the help of examples and investigate the equivalent conditions for each concept. In particular, we present the sucient conditions for maps to preserve some of separation axioms.
