I completed my four year Bachelor of Mathematics at Bogazici (Bosporus) University, Istanbul, Turkey in February 2007. Recently (February 2008), I got selected to Ph.D. program in Mathematics at Yeditepe University and I ranked first in the last semester among first year graduate students.
I was introduced to mathematics and the physical sciences while at school and it was in high school that I considered a career in this area. I noticed that I had good talent in Mathematics and got selected to the Mathematics department in the one of top ranked universities of Turkey. My undergraduate education at Bosporus University has not only given me a certain set of skills but has also helped me understand my fields of interest and my academic strengths and weaknesses. Through my undergraduate studies I've experienced some misfortunes. In my first semester I could not take final exams (I had operated due to hernia). Also due to shortage of time (1 hour exams) I could not demonstrate all of my potential. Because of all that I lost my concentration and motivation. However I made a new start after graduating from Bogazici University. In collaboration with Professors R. Agarwal, A. Ashyralyev, V. Shakhmurov I achieved significant results in long term projects and as a result I did some publications that are now submitted to SCI (science citation index) journals.(Actually one of them is accepted).
[1]. Maximal B-Regular Integro-Differential Equations.(To appear) Chinese Annals of Mathematics, Ser.B. (Joint with Veli Shakhmurov)
[2]. Operator-Valued (Lq,Lp) Fourier Multipliers. Submitted (Alone)
[3]. A Note On Integral Operators with operator valued kernels. Submitted (Alone)
[4]. Hausdorff-Youngs type Fourier multipliers and applications. Submitted (Alone)
[5]. High-accuracy difference schemes for differential equations of 2n-th order. Submitted (joint with Allaberen Ashyralyev)
[6]. Fourier multipliers on Banach-valued weighted Besov spaces and its applications. Submitted. (Joint with Ravi Agarwal and Veli Shakhmurov).
[7]. A note on the Taylor's decomposition on several points for the odd order differential equations. Submitted (joint with Allaberen Ashyralyev)
[8]. Operator-valued Fourier multipliers in Besov spaces and its applications. Submitted (Joint with Veli Shakhmurov).
I have been studying Differential equations, Difference equations and Harmonic analysis since 2007. I would like to state some of my results from above papers:
1
2
3
.....
Presently I am studying the following problems:
• Regularities and Asymptotic behaviors of some important dissipative Nonlinear Equations (Ginzburg-Landau, Whitham and etc. )
• Certain harmonic analysis tools to investigate nonlinear PDE.
• Investigation of Carleman estimates and unique continuation properties for elliptic diff. operator equations
• Utilizing Taylor difference schemes and exact difference schemes for equations
u⁽²ⁿ⁾(t)+Au(t)=f(t), u⁽²ⁿ⁻¹⁾(t)+Au(t)=f(t)
where A is unbounded positive definite self adjoint operator and f∈C^{α,α}((0,T),E) (Banach valued Holder spaces) and to establish stabilities of these schemes.
• Operator-valued averaging method (Krylov-Bogolyubov method) for
((d²u)/(dt²))+Au(t)+µf(u,((du)/(dt)))=0
where A is a positive definite operator µ<<1 small parameter and f∈L₂(R,H).
In February 2008, I got selected to Ph.D. program at Yeditepe University and I completed my first semster with rank one among first year graduate students. I took Functional analysis 2, Qualitative theory of ODE and Differential geometry courses in spring 2008. Moreover I regularly participated in Differential equations and Functional analysis workshops and I made several talks there.

c. Scalar and operator valued Fourier Multipliers in L_{p} spaces and applications.
Recently, I contacted with Professor Michael Klibanov. I wrote him about my wish to apply for PhD program at UNCC and he agreed to be my supervisor in Ph.D program. I would like to study ill-posed problems, numerical methods and Carleman estimates during my Ph.D studies. Therefore, I believe that under supervision of Professor Klibanov I can achieve significant results and I can gain scientific maturity. Taking everything into consideration I believe that UNCC is the best place for me to realize my academic plans and goals.
