    Shahriari, Mohammad؛ Vladicic, Vladimir (University of Maragheh, 2024-10-01)
    In this manuscript, the second order differential operators with constant delay and transmission boundary conditions are studied. The asymptotic forms of the characteristic functions and eigenvalues  of the operators are ...

  • Norm Retrievable Wavelet Systems 

    Aghaei, Mahdieh sadat؛ Hasankhani Fard, Mohammad Ali (University of Maragheh, 2024-10-01)
    This paper focuses on the norm retrieval problem for wavelet transform. The wavelet transform associated with an admissible wavelet is norm retrieval. However, this problem is difficult in special cases, i.e., for wavelet ...

  • Analyzing Functions Mapping the Unit Disk to Limaçon Domain 

    Soltani Masih, Vali؛ Najafzadeh, Shahram (University of Maragheh, 2024-10-01)
    This paper focuses on a particular type of starlike univalent function, namely $(1-sz)(1+z)$ with $-1/3\leq s\leq 1/3$. This function maps the open unit disk $\mathbb{D}$ onto a Limaçon domain denoted by \[ \left[(u-1)^2 ...

  • Pseudo-Duals of Frames and Modular Riesz Bases in Hilbert $C^\ast$-Modules 

    Mirzaee Azandaryani, Morteza (University of Maragheh, 2024-10-01)
    In the present article, duals, approximate duals and pseudo-duals (generated by bounded and not necessarily adjointable operators) of a frame in a Hilbert $C^\ast$-module are characterized and some of their properties are ...

  • Chebyshev Weighted Type Integral Inequality in Fuzzy and Abstract Spaces 

    Daraby, Bayaz؛ Vaezi, Zahra (University of Maragheh, 2024-10-01)
    In this paper, we express and prove Chebyshev weighted type inequality for fuzzy integrals and in abstract spaces where the functions are strictly monotone functions. Furthermore, we have shown our results for n-th strictly ...

  • Existence Results for an Implicit Coupled System Involving $\xi$-Caputo and $p$-Laplacian Operators
