About me:

My name is Matthew "Matt" Rosenzweig. I am a graduate student in mathematics at the University of Texas at Austin under the supervision of Professor Natasa Pavlovic in my final year. Previously, I completed my undergraduate degree at Harvard University. Here is a copy of my CV.

## Research Interests:

Research Interests:

My current research interests are in nonlinear partial differential equations and mathematical physics. More specifically, I have been recently interested in the mathematics of nonlinear dispersive and fluid equations and their derivation from underlying physical problems, such as water waves and quantum many-body systems. More on my mathematical interests can be learned from my research statement.

- Convolution inequalities for Boltzmann collision operator - These notes are based on the work by Alonso, Carneiro, and Gamba.
- Critical conditional global well-posedness and scattering for cubic NLS in $\mathbb{R}^{3}$ - These notes are based on the work by Kenig and Merle.
- Introduction to Fourier analysis on the torus -- These notes give an introduction to Fourier analysis on the torus $\mathbb{T}^{d}$. The notes include a treatment of Kolmogorov's construction of an $L^{1}(\mathbb{T})$ function whose Dirichlet means diverge pointwise almost everywhere.
