  • On a New G-Frame and Duality 

    Raisi Tousi, Reihaneh؛ Kamyabi Gol, Rajab Ali؛ Avazzadeh, Hosein (Vali-e-Asr university of Rafsanjan, 2018-08-01)
    We introduce a new g-frame (singleton g-frame), g-orthonormal basis and g-Riesz basis and study corresponding notions in some other generalizations of frames.Also, we investigate duality  for some kinds of g-frames. ...

  • Some Results on Convex Spectral Functions: I 

    Sattarzadeh, Ali Reza؛ Mohebi, Hossein (Vali-e-Asr university of Rafsanjan, 2018-08-01)
    In this paper, we give a fundamental convexity preserving for spectral functions. Indeed, we investigate infimal convolution, Moreau envelope and proximal average for convex spectral functions, and show that this properties ...

  • The Sign-Real Spectral Radius for Real Tensors 

    Afshin, Hamid Reza؛ Shojaeifard, Ali Reza (Vali-e-Asr university of Rafsanjan, 2018-08-01)
    In this paper a new quantity for real tensors, the sign-real spectral radius, is defined and investigated. Various characterizations, bounds and some properties are derived. In certain aspects our quantity shows similar ...

  • p-adic Shearlets 

    Fatemidokht, Mahdieh؛ Askari Hemmat, Ataollah (Vali-e-Asr university of Rafsanjan, 2018-08-01)
    The field $Q_{p}$ of $p$-adic numbers is defined as the completion of the field of the rational numbers $Q$ with respect to the  $p$-adic norm $|.|_{p}$. In this paper, we study the continuous and discrete $p-$adic shearlet ...

  • A Necessary Condition for a Shearlet System to be a Frame via Admissibility 

    Aminkhah, Mojgan؛ Askari Hemmat, Ataollah؛ Raisi Tousi, Reihaneh (Vali-e-Asr university of Rafsanjan, 2018-08-01)
    Necessary conditions for  shearlet  and cone-adapted shearlet systems to be frames are presented with respect to the admissibility condition of generators.

  • Banach Pair Frames 

    Fereydooni, Abolhassan؛ Safapour, Ahmad (Vali-e-Asr university of Rafsanjan, 2018-08-01)
    In this article, we consider pair frames in Banach spaces and   introduce Banach pair frames. Some various concepts in the frame theory such as frames, Schauder frames, Banach frames and atomic decompositions are considered ...
