The existence of equilibrium in a simple exchange model
, 2013 This paper gives a new proof of the existence of equilibrium in a simple model of an exchange economy. We first formulate and prove a simple combinatorial lemma and then we use it to prove the existence of equilibrium.

Partial metric spaces with negative distances and fixed point theorems [PDF]
, 2015 In this paper we consider partial metric spaces in the sense of O'Neill. We introduce the notions of strong partial metric spaces and Cauchy functions.

Some Notes on Fixed Point Theorems in ν-generalized Metric Spaces [PDF]
, 2015 We study ν-generalized metric spaces. We first study the concept of Cauchy sequence. We next give a proof of the Banach contraction principle in ν-generalized metric spaces.

On Hilbert Functions of Points in Projective Space and Structure of Graded Modules
, 2018 In this paper, we investigate the relationship between the Hilbert functions and the associated properties of the graded modules. To attain this, we construct the graded modules from the sets of points in projective space, $\mathbb{P}_k^n$ .

Set-valued mapping and Rough Probability
, 2017 In 1982, the theory of rough sets proposed by Pawlak and in 2013, Luay concerned a rough probability by using the notion of Topology. In this paper, we study the rough probability in the stochastic approximation spaces by using set-valued mapping and ...

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaIn this article, we introduce the Boyd-Wong type multivalued contractions and demonstrate that such mappings have a fixed point. Additionally, we look at the solvability of a few (k – ~)-Hilfer initial value fractional differential inclusions of order n −
