    Let P(𝑛) = F2[𝑥1, . . . , 𝑥𝑛] be the polynomial algebra in 𝑛 variables 𝑥𝑖, of degree one, over the field F2 of two elements. The mod-2 Steenrod algebra A acts on P(𝑛) according to well known rules. A major problem ...
  • A unified approach to integration theory 

    Robdera, Mangatiana A. (International Journal of Applied Physics and Mathematics,, 2019-01)
    We investigate the common features and the resemblance of the central parts of the different existing integration theories to obtain a more unified approach to the notion of integral. Our approach gives a presentation of ...

    Robdera, Mangatiana A. (NISC (Pty) Ltd,, 2015-12-14)
    We present a Riesz representation theorem in the setting of extended integration theory as introduced in [6]. The result is used to obtain boundedness theorems for integral operators in the more general setting of spaces ...
  • Fundamental Theorem of Calculus in Topological Vector Spaces

    Robdera, Mangatiana A. (International Journal of Applied Physics and Mathematics,, 2017-04)
    The notion of Cartesian net is introduced in order to provide an appropriate setting for the notion of double limit for directed functions defined on Cartesian products of spaces. As an application, we obtain extensions ...
  • On size function topology and fixed point theorems 

    Robdera, Mangatiana A. (International Scientific Publications and Consulting Services,, 2017-06)
    In this paper, we introduce and study a metric-like (non-necessarily metric) topology that is weaker than the original topology of a given topological space. The results are used to provide more useful and more general ...

  • On the subspace problem for Quasi-normed spaces 

    Robdera, Mangatiana A. (ScienceDomain International;, 2016-07-02)
    A definitive positive answer to the so-called proper subspace problem (a.k.a. the atomic space problem) for quasi-normed spaces is given: every infinite dimensional quasi-normed space has a proper closed infinite-dimensional ...

  • On summable bases in Banach spaces 

    Robdera, Mangatiana A. (Science Domian International,, 2014-06-24)
    We introduce the notion of summable bases that naturally generalizes the notion of unconditional sequence bases for Banach spaces. We shall be particularly interested in some classical results on sequences and series in ...
  • A new general approach to vector valued stochastic integration 

    Robdera, Mangatiana A. (International Journal of Modeling and Optimization,, 2014-08)
    We use an extended theory of integral that generalizes the integration of vector valued functions with respect to non-negative, monotonic,countably subadditive set functions, in order to introduce a new approach to stochastic ...

    Robdera, Mangatiana A. (Pushpa Publishing House,, 2010-10)
    In this note, we propose a more efficient approach to the definition of the integral of Banach-valued functions that enables us to give an improved version of the Orlicz-Pettis theorem for integrals.
