Fernique's theorem is a result in probability theory, particularly in the context of Gaussian processes and stochastic analysis. It deals with the continuity properties of stochastic processes, specifically the continuity of sample paths of certain classes of random functions.
A finite measure is a mathematical concept in the field of measure theory, which is a branch of mathematics that studies measures, integration, and related concepts. Specifically, a measure is a systematic way to assign a number to subsets of a set, which intuitively represents the "size" or "volume" of those subsets.
In functional analysis, "girth" typically refers to a concept related to certain geometric properties of the unit ball of a normed space or other related structures, particularly in the context of convex geometry and Banach spaces. While "girth" is most commonly used in graph theory to denote the length of the shortest cycle in a graph, in functional analysis, it can be associated with the geometric characterization of sets in normed spaces.
A **Grothendieck space** typically refers to a specific kind of topological vector space that is particularly important in functional analysis and the theory of distributions. Named after mathematician Alexander Grothendieck, these spaces have characteristics that make them suitable for various applications, including the theory of sheaves, schemes, and toposes in algebraic geometry as well as in the study of functional spaces.
Noncommutative measure and integration are concepts that arise in the context of noncommutative probability theory and functional analysis. Traditional measure theory and integration, such as Lebesgue integration, are based on commutative algebra, where the order of multiplication of numbers does not affect the outcome (i.e., \(a \cdot b = b \cdot a\)).
Radó's theorem is a result in complex analysis and the theory of Riemann surfaces. It states that any analytic (holomorphic) function defined on a compact Riemann surface can be extended to a function that is also holomorphic on a larger Riemann surface, provided the larger surface has the same genus as the compact surface.
Teichmüller modular forms are a class of mathematical objects that arise in the study of Teichmüller theory, which is a branch of mathematics dealing with the moduli spaces of Riemann surfaces. Specifically, these modular forms are associated with the deformation theory of complex structures on Riemann surfaces as well as with the geometry of the moduli space of stable curves and Riemann surfaces.
The uncertainty exponent is a concept often associated with the field of information theory, signal processing, and statistics. It typically quantifies the degree of uncertainty or variability associated with a particular measurement or estimate. The specific context can vary, but it's commonly used in the analysis of signals, data compression, or estimation theory. In a more technical sense, the uncertainty exponent \( \alpha \) can refer to the growth rate of uncertainty in a system or the behavior of a probability distribution.
A weakly harmonic function is a function that satisfies the properties of harmonicity in a "weak" sense, typically using the framework of distribution theory or Sobolev spaces.
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.
Alessio Figalli is an Italian mathematician renowned for his work in the field of calculus of variations, partial differential equations, and optimal transport. He was awarded the Fields Medal in 2018, one of the highest honors in mathematics, recognizing his significant contributions to mathematical analysis and its applications.
Alfred Tauber is a philosopher and prominent figure in the field of the philosophy of science and medicine, particularly known for his work on the philosophy of immunology. He has focused on the conceptual and epistemological foundations of the life sciences, especially how scientific knowledge is constructed and understood in the context of biological phenomena. Tauber's writings often explore the intersections of biology, medicine, and philosophy, raising questions about the nature of health, illness, and the immune system.
Bernard Bolzano (1781–1848) was a Czech philosopher, mathematician, and logician, known for his contributions to the foundations of mathematics and for his work in various fields, including ethics and theology. He made significant advances in the understanding of real numbers and continuity, and is credited with early developments in the concept of limits and the notion of a function.
Edward Charles Titchmarsh (1888–1963) was a prominent British mathematician and astronomer, known particularly for his contributions to the fields of analysis, number theory, and astronomy. He is perhaps best remembered for the Titchmarsh theorem in analytic number theory, which deals with the distribution of prime numbers. Additionally, Titchmarsh made significant contributions to the study of function theory and Fourier series.
Errett Bishop (1928–2019) was a prominent American mathematician known for his significant contributions to functional analysis and mathematical pedagogy. He is particularly well-known for his work in the foundations of mathematics, especially in the field of constructive mathematics. Bishop advocated for a constructive approach to analysis, which emphasizes the importance of providing explicit examples and methods for proving the existence of mathematical objects rather than relying on non-constructive methods prevalent in classical mathematics.
Micro Machines is a brand and line of toy vehicles that are miniature in size. First introduced by Galoob in 1987, these toys consist of tiny cars, trucks, and other vehicles, often accompanied by playsets that feature intricate environments and designs. The appeal of Micro Machines lies in their small scale, allowing for a wide variety of designs and configurations. In addition to the toy line, Micro Machines gained popularity through video games, especially during the 1990s.
Frederick Valentine Atkinson (also known as F.V. Atkinson) was a prominent American astronomer known for his contributions to the study of celestial mechanics and astrophysics. He is particularly recognized for his research on the behavior of celestial bodies and the mathematical modeling of their movements. His work has had a lasting impact on the field of astronomy, though specific details about his life and major discoveries may not be widely known.
Georges Glaeser is not widely recognized in mainstream contexts, and there may be multiple individuals with that name across various fields. However, one prominent Georges Glaeser is known in the academic and professional realms, particularly in areas related to technology and communications. It's possible that Georges Glaeser could refer to someone involved in a specific industry or field, but without more context, it is difficult to provide accurate information.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
