  • A study on the continuity of some classes of $ E $-$\mathbb {Q} $-convex functions 

    Heydarpour, Zohreh؛ Aghajani, Masoumeh (Vali-e-Asr university of Rafsanjan, 2023-12-01)
    As a generalization of convexity,  $ E $-convexity has been defined and studied in many publications. In this study, we recall the class of $ E $-$\mathbb {Q} $-convex sets, $ E $-$ \mathbb {Q}  $-convex and $ E $-additive ...

  • Hermite-Hadamard Type Inequalities for Sub-Topical Functions 

    Daryaei, Mohammad Hossein (Vali-e-Asr university of Rafsanjan, 2023-12-01)
    In this paper, we study Hermite-Hadamard type inequalities for sub-topical (increasing and plus sub-homogeneous) functions in the framework of abstract convexity. Some examples of such inequalities for functions defined ...

  • $C$-spectral norm inequalities between operator matrices and their entries 

    Rezagholi, Sharifeh؛ Hosseini, Mahya (Vali-e-Asr university of Rafsanjan, 2023-12-01)
    In this paper, the notion of $C-$spectral norm is introduced for operators; it was defined and studied for matrices before. Here, some $C-$spectral norm inequalities between operator matrices and their operator entries, ...

  • Spectral clustering by considering stationary distribution vector and transition matrix 

    Vaziri, Elaheh؛ Jamshidi, Mina؛ Motallebi, Hassan (Vali-e-Asr university of Rafsanjan, 2023-12-01)
    One of the popular methods of data clustering is spectral clustering. The main step of this method is constructing a graph representation of the data set and its similarity matrix. The similarity matrices which are constructed ...

  • Localization Operators on Sobolev Spaces 

    Esmaeelzadeh, Fatemeh (Vali-e-Asr university of Rafsanjan, 2023-12-01)
    In this paper,  we discuss some generalizations coming from wavelet transform on Sobolev spaces. In particular, we introduce the bounded localization operators on Sobolev spaces which are related to multi-dimensional wavelet ...

  • cK-frames and cK-Riesz bases in Hilbert spaces 

    Shekari, Azam؛ Abdollahpour, Mohammad Reza (Vali-e-Asr university of Rafsanjan, 2023-12-01)
    In this paper, we prove some new results about cK-frames. Also, we introduce the concept of cK-Riesz basis and we provide a necessary and sufficient condition under which $F$ is a cK-Riesz basis. Finally, for the closed ...
