Probability theorists are mathematicians or researchers who specialize in the study of probability theory, which is a branch of mathematics dealing with the analysis of random events and the likelihood of various outcomes. Probability theory provides the mathematical framework to model uncertain situations, helping to quantify the likelihood of events and to make predictions based on observed data. Key areas in the study of probability theory include: 1. **Random Variables**: Understanding the behavior of variables that can take on different values based on chance.

PDE theorists are researchers and mathematicians who specialize in the study of partial differential equations (PDEs). PDEs are equations that involve functions of several variables and their partial derivatives. They are fundamental in various fields of science and engineering because they can describe a wide range of physical phenomena, including heat transfer, fluid dynamics, wave propagation, and electromagnetism.

Measure theory is a branch of mathematics that deals with the study of measures, integration, and the properties of measurable functions. It provides a rigorous framework for understanding concepts such as length, area, volume, and probability. A **measure** is a systematic way to assign a numerical value (non-negative) to subsets of a given space, which can be thought of as a generalized notion of size.

Approximation theorists are mathematicians or researchers who specialize in the field of approximation theory. This area of mathematics deals with how functions can be approximated using simpler or more manageable forms, such as polynomials, trigonometric functions, or other basis functions. The primary focus is on understanding the ways in which functions can be estimated or represented using finite-dimensional subspaces, as well as quantifying the error involved in such approximations.

Zubov's method refers to a mathematical approach used primarily in the field of dynamical systems, particularly for analyzing the stability of solutions to differential equations. This method is named after the Russian mathematician V.I. Zubov, who contributed to the study of stability theory. In essence, Zubov's method deals with determining the stability of equilibrium points by constructing Lyapunov functions and using them to assess the behavior of trajectories in the vicinity of these points.

Zahorski's theorem is a result in the field of mathematical analysis and set theory, particularly dealing with properties of Baire spaces. Specifically, it pertains to the existence of certain types of functions or mappings in the context of continuous functions in Baire spaces.
