Sufficient conditions for existence of common $L$-fuzzy fixed points under such contractions are also investigated. The established ideas are generalizations of many concepts in fuzzy mathematics. In the case where our postulates are reduced to their classical variants, the concept presented herein merges and extends several significant and well-known fixed point theorems in the setting of both single-valued and multi-valued mappings in the corresponding literature of discrete and computational mathematics. A few of these special cases are pointed out and discussed. In support of our main hypotheses, a nontrivial example is provided.University of MaraghehSahand Communications in Mathematical Analysis2322-580718320210801A Generalized Class of Univalent Harmonic Functions Associated with a Multiplier Transformation273924432610.22130/scma.2021.132155.841ENDeeplaiKhuranaDepartment of Mathematics, Sant Longowal Institute of Engineering and Technology, Longowal, Punjab, India.Department of Mathematics, Hans Raj Mahila Maha Vidyalya, Jalandhar-144001, Punjab, India.Raj KumarGargDepartment of Mathematics, DAV University, Jalandhar-144001, Punjab, India.0000-0001-9277-0915SarikaVermaDepartment of Mathematics, DAV University, Jalandhar-144001, Punjab, India.GangadharanMurugusundaramoorthySchool of Advanced Science,Vellore Institute of technology Deemed to be University, Vellore - 632014, India.0000-0001-8285-6619Journal Article20200804We define a new subclass of univalent harmonic mappings using multiplier transformation and investigate various properties like necessary and sufficient conditions, extreme points, starlikeness, radius of convexity. We prove that the class is closed under harmonic convolutions and convex combinations. Finally, we show that this class is invariant under Bernandi-Libera-Livingston integral for harmonic functions.University of MaraghehSahand Communications in Mathematical Analysis2322-580718320210801On Some Linear Operators Preserving Disjoint Support Property414924493910.22130/scma.2021.115697.690ENNohaEftekhariDepartment of pure Mathematics, Faculty of Mathematical Sciences,

We show that the constant coefficients of all isometries on $lpi$ are in the class of such operators, where $2neq pin [1,infty )$ and $I$ is a non-empty set. We extend preserving disjoint support property to linear operators on $mathfrak{c}_{0}(I).$ At the end, we obtain some equivalent properties of isometries on Banach spaces.University of MaraghehSahand Communications in Mathematical Analysis2322-580718320210801Existence and Uniqueness for a Class of SPDEs Driven by L'{e}vy Noise in Hilbert Spaces516824494010.22130/scma.2021.520720.884ENMajidZamaniDepartment of Mathematics and Computer Sciences, Amirkabir University of Technology, Tehran, Iran.S.

We also extend some classical results from frames theory to bc-frames and show that some of them do not remain valid for bc-frames in general. The construction of bc-frame operators and Weyl--Heisenberg bc-frames are also discussed.University of MaraghehSahand Communications in Mathematical Analysis2322-580718320210801Integral $K$-Operator Frames for $End_{mathcal{A}}^{ast}(mathcal{H})$9110724509310.22130/scma.2021.140176.874ENHatimLabriguiDepartment of Mathematics, Faculty of Science, University of Ibn Tofail, B.P. 133, Kenitra, Morocco.0000-0001-8807-487XSamirKabbajDepartment of Mathematics, Faculty of Science, University of Ibn Tofail, B.P. 133, Kenitra, Morocco.0000000197179366Journal Article20201120In this work, we introduce a new concept of integral $K$-operator frame for the set of all adjointable operators from a Hilbert $C^{ast}$-module $mathcal{H}$ to itself denoted by $End_{mathcal{A}}^{ast}(mathcal{H}) $.
