(World Scientific Publishing, 2019-07)Poor living conditions, overcrowding and strain diversity are some of the factors that influence mixed infection in Tuberculosis (TB) at the population level. We formulate a mathematical model for mixed infection in TB ...

(Elsevier, 2019-04)Vector control is critical to limit the circulation of vector-borne diseases, like chikungunya, dengue or zika, which have become important issues around the world. Among them, the Sterile Insect Technique (SIT) and the ...
-
(Taylor and Francis, 2019)This paper focuses on the students who are registered in the University of Pretoria’s academic development programme, named the Four-year Programme (FYP). The programme was introduced as a gateway for students who are ...
-
(American Institute of Mathematical Sciences, 2019-10)In this paper we consider discrete growth-decay-fragmentation equa-tions that describe the size-distribution of clusters that can undergo splitting, growth and decay. The clusters can be for instance animal groups that can ...

(NISC (Pty) Ltd and Informa UK Limited (trading as the Taylor & Francis Group), 2020)Sibling curves are a new way to represent the zeroes of any complex-valued function. Interesting results are already known for the sibling curves of quadratic polynomials. In this article a complete investigation of sibling ...

(American Institute of Physics, 2018-10)The long term properties, like co-existence and extinction, are usually determined by the demographics of the competing species or other competitive advantages. In this paper we consider the effect of conspecific support ...

(Operations Research Society of South Africa, 2018-11-04)Recently, Ross derived a theorem, namely the “Recovery Theorem”, that allows for the recovery of the pricing kernel and real-world asset distribution, under particular assumptions, from a forward-looking risk neutral ...
-
(American Institute of Mathematical Sciences, 2019-11)In this note we prove the existence and uniqueness of local maximal smooth solution of the stochastic simplified Ericksen-Leslie systems modelling the dynamics of nematic liquid crystals under stochastic perturbations.
-
Optimal asset allocation for a DC plan with partial information under inflation and mortality risks (Taylor and Francis, 2021)We study an asset allocation stochastic problem for a defined-contribution pension plan during the accumulation phase. We consider a financial market composed of a risk-free asset, an inflation-linked bond and the risky ...
-
(Association for Mathematics Education of South Africa, 2018)One of the great joys of mathematics is finding multiple ways of arriving at a solution or proving a result. Some approaches can be messy and longwinded, while others can be elegant and succinct. But the joy lies in arriving ...

(Springer, 2019-09)It is proved that every prevariety of algebras is categorically equivalent to a ‘prevariety of logic’, i.e., to the equivalent algebraic semantics of some sentential deductive system. This allows us to show that no nontrivial ...

(University of Nis, Serbia, Faculty of Sciences and Mathematics, 2019)In this paper, we introduce some new notions such as interval valued neutrosophic soft points, interval valued neutrosophic soft mappings, interval valued neutrosophic soft Hausdor topological spaces, and interval valued ...

Fixed points of Suzuki-type generalized multivalued (f, θ, L)- almost contractions with applications (University of Nis, Serbia, Faculty of Sciences and Mathematics, 2019)In this paper, we define Suzuki type generalized multivalued almost contraction mappings and prove some related fixed point results. As an application, some coincidence and common fixed point results are obtained. The ...
-
(Hindawi Publishing, 2019-02-17)In this paper, we will introduce the concept of Suzuki type multivalued (θ,R)-contraction and we will prove some fixed point results in the setting of a metric space equipped with a binary relation. Our results generalize ...
