The Kneser–Tits conjecture is a statement in the field of algebraic groups and the theory of group actions, particularly concerning the structure of algebraic groups and their associated buildings. It was proposed by mathematicians Max Kneser and Jacques Tits. The conjecture pertains to the relationship between a certain class of algebraic groups defined over a field and their maximal compact subgroups.
The Koecher–Maass series is a mathematical series that arises in the context of the theory of modular forms and automorphic forms. It is named after mathematicians Martin Koecher and Hans Maass, who contributed to the understanding of modular forms and their properties. The series itself is typically associated with the theory of modular forms on the upper half-plane. These forms are complex functions that are not only continuous but also satisfy certain transformation properties under the action of the modular group.
Konrad Knopp was a notable German mathematician recognized for his work in the field of analysis, particularly in functional analysis and the theory of functions. He is most known for his contributions to the theory of Fourier series and for his textbook "Theory and Applications of Infinite Series." This work covers various topics related to series, convergence, and summation methods. Knopp's contributions also include studying different summability methods, convergence criteria, and their applications in mathematical analysis.

The Kotcherlakota Rangadhama Rao Memorial Lecture Award is an honor awarded to individuals in recognition of their contributions to the field of anatomy and medicine in India. It commemorates the legacy of Dr. Kotcherlakota Rangadhama Rao, who was a prominent figure in anatomy education and research. The award typically involves a lecture or presentation delivered by the recipient on a specified topic related to anatomy.
Krein's condition refers to a specific criterion used in the mathematical field of functional analysis, particularly in the study of operators on Hilbert spaces. It is particularly associated with the stability of operators and the spectral properties of certain classes of linear operators, especially in the context of self-adjoint operators. In its most well-known form, Krein's condition provides a way to characterize the stability of a linear operator with respect to perturbations.
Krzysztof Antoni Meissner is a Polish scientist known for his work in various fields including chemistry and materials science. However, he may not be widely recognized outside specific academic circles or specialized fields.
Laboratori Nazionali di Frascati (LNF) is a research facility located in Frascati, Italy, and is part of the Italian National Institute for Nuclear Physics (INFN). Established with the aim of conducting fundamental research in the fields of nuclear and particle physics, LNF is equipped with advanced particle accelerators and various experimental facilities.
Lambert's cosine law, also known as Lambert's law of illumination, describes how the intensity of light (or radiation) received from a surface changes with the angle of incidence relative to the surface normals. According to this law, the illuminance (or intensity of light) on a surface is directly proportional to the cosine of the angle between the surface normal and the direction of the light source.
Land cover refers to the physical and biological cover of the Earth's surface, including natural landscapes, human-made structures, and various ecosystems. It encompasses the types of vegetation, soil, water bodies, and manmade features that occur in a given area. Land cover can be characterized in various ways, including: 1. **Natural Vegetation:** Forests, grasslands, wetlands, and deserts. 2. **Agricultural Lands:** Croplands, pastures, orchards, and agricultural fields.
Language acquisition by deaf children refers to the process through which children who are deaf or hard of hearing develop language skills. This process can differ significantly from that of hearing children because deaf children may not have access to spoken language in the same way that hearing children do, particularly if they are born to hearing parents who do not know sign language.
A **large diffeomorphism** refers to a diffeomorphism (a smooth, invertible map between differentiable manifolds with a smooth inverse) that can be smoothly deformed or transformed into another diffeomorphism in a way that allows for a significant change in the structure of the manifold. This concept is commonly encountered in the fields of differential geometry and topology.
Larry D. McLerran is a prominent American theoretical physicist, known for his contributions to the fields of quantum chromodynamics (QCD) and particle physics. He is particularly recognized for his work on the properties of nuclear matter under extreme conditions, such as those found in heavy-ion collisions. McLerran has been instrumental in the development of theoretical frameworks that describe the behavior of quark-gluon plasma, a state of matter believed to have existed shortly after the Big Bang.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.
