Where Do I Work?

University of Toledo

Department of Mathematics and Statistics

Position: Graduate Teaching Assistant

Department Phone: 419-530-2568

Education

I am in the final year of my Ph.D. in Pure Mathematics at the University of Toledo.

University of Toledo

Degree: Ph.D. in Pure Mathematics

Subjects: Operator Theory, Complex Analysis, and Functional Analysis

Thesis: Invertibility of Toeplitz Operators via Berezin Transforms

Advisor: Professor Željko Čučković

University of Toledo

Degree: Master of Arts

Subject: Pure Mathematics

University of Toledo

Degree: Bachelor of Science

Subject: Pure Mathematics, Physics Concentration

My Research

I study Operator Theory on Spaces of Holomorphic Functions, including the Bergman, Hardy, Segal-Bargmann Spaces, and Model spaces. Topics include invertibility, positivity, compactness, boundedness, and invariant subspaces of Toeplitz, Hankel, and composition operators.

My Papers

Carleson measures and Douglas' question on the Bergman space

with Željko Čučković, 2017 To appear in Rendiconti del Circolo Matematico di Palermo.

Motivated by Douglas' question about the invertibility of Toeplitz operators on the Hardy Space, we study a related question concerning the Berezin transform and averaging function of a Carleson measure for the weighted Bergman space of the disc. As a consequence, we obtain a necessary and sufficient condition for the invertibility of Toeplitz operators whose symbols are averaging functions of these Carleson measures.

Invertibility and Positivity of Truncated Toeplitz Operators on Certain Model Subspaces of the Hardy Space

with Krishna Subedi, submitted to Archiv der Mathematik in October 2017.

We study the degree to which both the invertibility and positivity of certain Truncated Toeplitz Operators are determined by the Berezin transforms of their symbols on Model Subspaces of the Hardy Space corresponding to the inner functions $u = z^2$ and $u = z^3$.

Carleson measures and Douglas' question on the Bargmann-Fock space

with Željko Čučković, 2017.

Student Evaluations

"Anthony is a great instructor, and definitely cares more about his job than any professor I've seen."

"Mr. Vasaturo is the best math instructor that I've had at the University of Toledo. He is very thorough with his lectures and always tries to make sure that students have a real understanding of the material before moving on to the next topic. He was very easy to work with as far as homework and tests. I wish he taught more advanced math classes."

"Vasaturo concisely teaches what is relevant, reviews appropriately before exams, communicates effectively via email, and on a daily basis encourages students to ask for help and reminds us that he is available for tutoring at the library. He's also down to earth, approachable, very laid back which is important. Great professor!"

"Anthony was a great instructor. He was very clear on what information we needed to know for exams. Homework wasn't heavy and he answered homework questions every class if you had them. He was awesome!"

"He always lets you feel comfortable that you can ask him about any sentence he said in class, at any time."

"The instructor is always so helpful, enthusiastic, and encouraging without fail. I feel he personally wants me to succeed."

"Anthony really does an excellent job. He has the fastest response rate of any professor I've had."

"I'm actually never happy if I have to miss the class. Professor Anthony is really good at driving the concepts of Calculus home in a way my previous instructor did not. I really do appreciate the effort he puts in."
