[ 1 ] - The norm of pre-Schwarzian derivatives on bi-univalent functions of order $alpha$
In the present investigation, we give the best estimates for the norm of the pre-Schwarzian derivative $ T_{f}(z)=dfrac{f^{''}(z)}{f^{'}(z)} $ for bi-starlike functions and a new subclass of bi-univalent functions of order $ alpha $, where $Vert T_{f} Vert= sup_{|z|
[ 2 ] - Stability for certain subclasses of harmonic univalent functions
In this paper, the problem of stability for certain subclasses of harmonic univalent functions is investigated. Some lower bounds for the radius of stability of these subclasses are found.
[ 3 ] - Some properties of analytic functions related with bounded positive real part
In this paper, we define new subclass of analytic functions related with bounded positive real part, and coefficients estimates, duality and neighborhood are considered.
[ 4 ] - Ozaki's conditions for general integral operator
Assume that $mathbb{D}$ is the open unit disk. Applying Ozaki's conditions, we consider two classes of locally univalent, which denote by $mathcal{G}(alpha)$ and $mathcal{F}(mu)$ as follows begin{equation*} mathcal{G}(alpha):=left{fin mathcal{A}:mathfrak{Re}left( 1+frac{zf^{prime prime }(z)}{f^{prime }(z)}right) <1+frac{alpha }{2},quad 0<alphaleq1right}, end{equation*} and begin{equation*} ma...

In this work, applying Lemma due to Nunokawa et. al. cite{NCKS}, we obtain some sufficient inequalities for some certain subclasses of univalent functions.
[ 6 ] - Some Properties of Reproducing Kernel Banach and Hilbert Spaces
This paper is devoted to the study of reproducing kernel Hilbert spaces. We focus on multipliers of reproducing kernel Banach and Hilbert spaces. In particular, we try to extend this concept and prove some related theorems. Moreover, we focus on reproducing kernels in vector-valued reproducing kernel Hilbert spaces. In particular, we extend reproducing kernels to relative reproducing kernels an...
[ 7 ] - توزیع بهینه منابع بودجه استانی بر پایه یک مدل کنترل بهینه
هدف این مطالعه، ارائه مدلی جهت تخصیص بهینه استانی منابع بودجهای با توجه به اولویتهای استانها و در راستای رفع تمرکز مالی و عدم تعادل فضایی کشور و کاهش نابرابری های منطقهای است، به نحوی که حداکثر رفاه اجتماعی را تضمین نماید. برای این منظور یک مدل پویا مبتنی بر نظریه کنترل بهینه طراحی شده و نقطه تعادل بلند مدت این مدل که بیانگر سطوح بهینه تخصیص منابع مالی به استانهای کشور است، با تمرکز بر 12...
[ 8 ] - Regularity of Bounded Tri-Linear Maps and the Fourth Adjoint of a Tri-Derivation
In this Article, we give a simple criterion for the regularity of a tri-linear mapping. We provide if f : X × Y × Z −→ W is a bounded tri-linear mapping and h : W −→ S is a bounded linear mapping, then f is regular if and only if hof is regular. We also shall give some necessary and sufficient conditions such that the fourth adjoint D^∗∗∗∗ of a tri-derivation D is again tri-derivation.
[ 9 ] - Joint and Generalized Spectral Radius of Upper Triangular Matrices with Entries in a Unital Banach Algebra
In this paper, we discuss some properties of joint spectral {radius(jsr)} and generalized spectral radius(gsr) for a finite set of upper triangular matrices with entries in a Banach algebra and represent relation between geometric and joint/generalized spectral radius. Some of these are in scalar matrices, but some are different. For example for a bounded set of scalar matrices,$Sigma$, $r_*...
