Integral geometry is a branch of mathematics that focuses on the study of geometric measures and integration over various geometric objects. It combines techniques from geometry, measure theory, and analysis to explore properties of shapes, their sizes, and how they intersect with each other. One of the key concepts in integral geometry is the use of measures defined on geometric spaces, which allows for the formulation of results about lengths, areas, volumes, and higher-dimensional analogs.
The Borell–Brascamp–Lieb (BBL) inequality is a result in the field of measure theory and functional analysis, particularly in the study of convex functions and their relationships to volume measures and integrals. It generalizes several well-known inequalities, including the Brunn-Minkowski inequality. The inequality provides a way to compare the integrals of convex functions with respect to measures that are related through certain kinds of convex combinations.
Buffon's noodle is a problem in geometric probability that involves dropping a noodle (or a long, thin stick) on a plane with parallel lines drawn on it and calculating the probability that the noodle will cross one of the lines. This problem was first posed by the French mathematician Georges-Louis Leclerc, Comte de Buffon, in the 18th century.
The Funk transform is a mathematical tool that arises in the context of functional data analysis and is used for various applications in spatial data representation and multidimensional data analysis. Specifically, it can be employed in inverse problems, such as those found in medical imaging and geophysical applications. In essence, the Funk transform generalizes the Fourier transform to higher dimensions and is particularly useful for analyzing functions defined on the surface of a sphere or in other complex geometries.
Hadwiger's theorem is a fundamental result in graph theory, which relates to the colorability of graphs.

Established in Yerevan, the capital of Armenia, it plays a critical role in advancing mathematical research and education in the country. The institute is involved in various areas of mathematics, including pure and applied mathematics, and it often collaborates with international researchers and academic institutions.
Mean width is a geometric concept used to describe the average distance across a shape or object in various dimensions. It is particularly common in the study of convex shapes, where it helps characterize their size and form. In two dimensions, the mean width of a convex shape is defined as the average of the distances from the shape to a set of parallel lines that sweep through the shape.
The Penrose transform is a mathematical tool that arises in the context of twistor theory, a framework formulated by physicist Roger Penrose in the 1960s. The primary aim of twistor theory is to reformulate certain aspects of classical and quantum physics, particularly general relativity, in a way that simplifies the complex structures involved in these theories. **Key Concepts:** 1.
The Pompeiu problem is a classical question in geometry named after the Romanian mathematician Dimitrie Pompeiu. It involves the relationship between geometric shapes and their properties in relation to points within these shapes.
The Prékopa–Leindler inequality is a fundamental result in the field of convex analysis and probability theory. It provides a way to compare the integrals of certain convex functions over different sets.
The Radon transform is a mathematical integral transform that takes a function defined on a multi-dimensional space (usually \( \mathbb{R}^n \)) and produces a set of its integrals over certain geometric objects, typically lines or hyperplanes. Named after the Austrian mathematician Johann Radon, the transform is particularly important in the fields of image processing, computer tomography, and medical imaging.
Stochastic geometry is a branch of mathematics that deals with the study of random spatial structures and patterns. It combines elements from geometry, probability theory, and statistics to analyze and understand phenomena where randomness plays a key role in the geometric configuration of objects. Key concepts and areas of interest in stochastic geometry include: 1. **Random Sets**: Studying collections of points or other geometric objects that are distributed according to some random process.
