A function \( f: \mathbb{R}^n \to \mathbb{R} \) is called quasiconvex if, for any two points \( x, y \in \mathbb{R}^n \) and for any \( \lambda \in [0, 1] \), the following condition holds: \[ f(\lambda x + (1 - \lambda) y) \leq \max(f(x), f(y)).

Hans Krebs (1900-1981) was a distinguished British biochemist of German origin, renowned for his significant contributions to the field of biochemistry, particularly in understanding cellular respiration. He is best known for discovering the urea cycle and the citric acid cycle (also known as the Krebs cycle), both of which are fundamental metabolic pathways in living organisms.

James Ivory (1765–1842) was a Scottish mathematician and a prominent figure in the development of mathematical analysis and geometry during the late 18th and early 19th centuries. He is best known for his contributions to calculus and for his work on various mathematical problems, including those related to the theory of curves and surfaces. Ivory is also recognized for his contributions to the field of integral calculus and for his work on the moment of inertia in mechanics.

John Huxham is a notable figure primarily recognized for his work in the fields of organizational management and systems thinking. He is a professor, researcher, and consultant who has focused on collaboration and the dynamics of organizations. Huxham has been associated with various academic institutions and has contributed to the development of concepts related to managing partnerships, networks, and collaborative efforts within organizations. His work emphasizes the importance of understanding the complexities of collaborative processes and the challenges organizations face when trying to work together effectively.

Justus von Liebig (1803–1873) was a German chemist who is often referred to as one of the founding figures of organic chemistry. He made significant contributions to the fields of agricultural chemistry, biochemistry, and the study of the chemistry of living organisms. Liebig is best known for developing the concept of the synthesis of organic compounds and for his work on the importance of nitrogen in plant nutrition, which laid the groundwork for modern agricultural practices and fertilizer production.

Karl Gegenbaur (1826–1903) was a prominent German zoologist and paleontologist known for his work in evolutionary biology and comparative anatomy. He is often regarded as a founding figure in the field of evolutionary morphology, which studies the relationship between the structure of organisms and their evolutionary history. Gegenbaur made significant contributions to the understanding of the vertebrate skeleton and the classification of various animal groups.

Norman Pirie (1913-1997) was a notable British biochemist and virologist, best known for his pioneering research in the fields of plant viruses and molecular biology. He made significant contributions to the understanding of viral structures and the nature of genetic material. Pirie’s work helped to clarify the role of nucleic acids in the replication of viruses and advanced the study of virology, particularly in relation to plant pathogens.

The Dürer graph is a specific type of graph in the field of graph theory, named after the German painter and printmaker Albrecht Dürer. It is a highly symmetrical graph that has 12 vertices and 24 edges. The graph can be represented as a 3-dimensional object, which resembles a cube, and it is known for its interesting geometric properties.

The Generalized Petersen graph is a family of graphs that generalize the structure of the well-known Petersen graph. These graphs are denoted as \( GP(n, k) \), where \( n \) and \( k \) are positive integers. The Generalized Petersen graph is defined using two parameters: - \( n \): the number of vertices in the outer cycle (which is a simple cycle graph with \( n \) vertices).

In graph theory, a **snark** is a specific type of graph that has some interesting properties. Snarks are defined as: 1. **Cubic Graphs**: Snarks are always cubic, meaning every vertex in the graph has a degree of 3. 2. **Not 3-Colorable**: A characteristic feature of snarks is that they cannot be colored with 3 colors without having two adjacent vertices sharing the same color.

A Generalized Verma module is a concept from the representation theory of Lie algebras, particularly in the context of infinite-dimensional representations and the study of parabolic subalgebras.

KRI Rigel (933) is a vessel of the Indonesian Navy, specifically classified as a fast attack craft. It is part of the KCR-40 class, which encompasses a series of vessels designed primarily for patrol and surveillance duties. KRI Rigel is notable for its modern design and capabilities, which include engaging in anti-surface and anti-air operations. The ship is equipped with various weapons systems and advanced technology to fulfill its role in national defense and maritime security.

Myroxylon is a genus of tropical trees belonging to the legume family, Fabaceae. The most well-known species within this genus is Myroxylon balsamum, commonly referred to as balsam of Peru or Peru balsam. It is native to Central and South America, particularly found in countries like Peru, Ecuador, and Venezuela. The tree is notable for its fragrant resin, which has various applications in perfumery, cosmetics, and traditional medicine.

"Accumulatio" is a Latin term that generally translates to "accumulation" in English. The concept can refer to the gradual gathering or collecting of something over time. In various contexts, "accumulatio" might be used to describe financial accumulation (such as savings or investments), the accumulation of knowledge, or the gathering of resources and materials in different fields.

In algebra, a **transcendental extension** refers to a type of field extension that contains elements that are not algebraic over the base field. More formally, if \( K \) is a field, a field extension \( L \) of \( K \) is called a transcendental extension if there exists at least one element \( \alpha \in L \) such that \( \alpha \) is not the root of any non-zero polynomial with coefficients in \( K \).

Matthew of Vendôme (also known as Matheus Vendomensis or Matthaeus de Vendome) was a notable figure in the 12th century, primarily known for his contributions as a poet and grammarian. He is often associated with the development of medieval Latin literature and educational practices. His most recognized work is *De Arte Poetica*, which is a treatise on the art of poetry, drawing on classical sources and contributing to the rhetorical education of the time.

A short ton is a unit of mass commonly used in the United States and is equivalent to 2,000 pounds (lbs). The short ton is part of the customary system of measurements used primarily in the U.S., and it is often used in contexts like shipping, construction, and industry. In metric terms, a short ton is approximately equal to 907.185 kilograms.
