This book presents a collection of topics in partial differential equations designed to serve as a bridge to research for Master's students.

Drawing on material originally developed for student projects, the selected topics require only standard prerequisites such as differential calculus, complex analysis, Fourier analysis, the Lebesgue integral, and some functional analysis. They span a broad range of problems in PDE, including Burgers equation, the wave equation, spectral theory of the Laplacian, and harmonic functions. The topics and their presentation are intended to help readers access the research literature.

Offering a diverse set of themes that highlights the richness of the field and opens the door to research, this book will be of interest to graduate students studying PDEs. With original material closely related to the author s own research, it can also serve as a concise reference for researchers.
