- DescriptionThe UCF [Mathematics Colloquium](https://sciences.ucf.edu/math/colloquium/), held every Monday from 3:30 to 4:30 p.m. in MSB 318, offers a diverse platform for research scholars, faculty, students, and industry experts to share and exchange ideas, fostering discussion and networking across various areas of mathematics.
[Zeljko Cuckovic, Ph.D,](http://math.utoledo.edu/~zcuckov/) from University of Toledo will speak at this week's colloquium on invertibility of Toeplitz operators on the Bergman space.
Abstract: Characterizing invertibility of a Toelitz operator $T_\varphi$ on the Bergman space in terms of the properties of the symbol $\varphi$ has been a long standing open problem. Partial answers can be given by assuming the positivity of the symbol. In this talk we introduce a novel geometric condition on the image of the symbols, which relaxes the standard positivity condition. We will also discuss the related Douglas' problem.
