four color theorem
Any flat map can be colored using a maximum of four colors, provided that adjacent regions are not the same color. "The first famous theorem proven by a computer" 隣接関係そのものが建築の形を決める The walls and ceiling are divided like a "three-dimensional map" using gold, crimson, blue-green, and purple acoustic panels. The four colored polygonal regions are continuous from the outer shell to the ceiling, walls, seating area, and circulation paths. Mathematical Architecture space

Hutchinson's Theorem
Fractal shapes are always uniquely determined as a "combination of reduced copies". "By repeatedly shrinking, moving, and rotating a single architectural unit, the whole converges into a stable, self-similar form." The fundamental principle that makes all self-similar architecture possible 中央へ向かって形が無限に収束して見える部分が、定理における「唯一のフラクタル・アトラクター」を表現 The stage itself becomes the "attractor" in Hutchinson's theorem.

Hellley's Theorem
It is possible to determine whether many convex regions "have a common part as a whole" using only a small number of combinations. When you choose any three things, there is always a common element. A central point or shared space exists that satisfies all conditions. A theorem for finding the commonality of the whole from local overlaps. 複数の凸状ボリュームが重なり、中央の金色に光る共有アトリウムへ収束する The golden light represents the "common area" of each domain.

Titze's extension theorem
Values defined continuously within a closed subspace can be extended to the entire space while maintaining continuity, provided the conditions are favorable. This approach involves extending the "continuous conditions" such as light, temperature, sound, and density present in parts of existing buildings naturally into the city and surrounding space, rather than abruptly cutting them off at the boundary. 中央の明るいホールを「局所で定義された連続性」とし、屋根・床・テラス・階段・広場の水平レイヤーがそのまま外部へ拡張していく構成 A hall wh

Green's Theorem
The changes occurring within a region on a plane coincide with the flow that occurs when circling its boundary. "Reading the invisible forces within from the experience of boundaries" - Mathematics 外周を一周する金の回廊=境界の積分、中央の光る円形ホワイエ=内部の渦、という構成 The golden line represents the boundary, the central activity and the open space represent the internal "vortex." "Circling the outer perimeter" and "activities within" become a single spatial structure. Mathematical Architecture space

Jordan curve theorem
When you draw closed lines that do not intersect on a plane, the plane is always divided into an "inside" and an "outside". It is only by placing a continuous boundary that the concepts of "inside" and "outside" are created. ONE CONTINUOUS BOUNDARY CREATES INSIDE AND OUTSIDE. A single, non-intersecting closed curve forms the entire structure, clearly separating the central courtyard as the "inside" from the urban plaza as the "outside." The main entrance symbolizes the moment

Nash embedding theorem
"Curved space can be embedded into a higher-dimensional, ordinary Euclidean space without disrupting its distance or curvature." C1 Embedding Theorem Within the range of first-order differentiability, it can be embedded in surprisingly low dimensions. However, very fine waves and wrinkles may appear on the surface. Smooth embedding theorem While it's always possible to embed the image while maintaining smoothness, it requires a higher level of precision. A theory that transla

The potential of structural design that transcends gravity - New developments in structural design
In the world of architecture, defying gravity, a natural law, has long been both a dream and a challenge. Modern mathematical architecture translates abstract concepts such as chaos theory, topology, and higher-dimensional geometry into spatial ideas and visual forms, realizing innovative structural designs that transcend the conventional constraints of gravity. This article explores the possibilities of gravity-transcending structural design and provides a concrete explanati

K3 curved surface
"A four-dimensional complex surface with many holes, deep symmetry, and beautifully balanced curvature." K3 surfaces are smooth surfaces in complex 2D and real 4D, with a representative example being a quartic surface in projective space. 1. A type of Calabi-Yau K3 surfaces can be viewed as two-dimensional versions of Calabi-Yau manifolds; that is, highly balanced spaces where the curvatures cancel each other out as a whole. 2. The structure of the holes is rich. Unlike a sim

Homotopy theory
A mathematical and logical theory that considers "types of things" as "shapes of space." type = space Element = Point in space Equality = the path connecting two points Equality between equals = Transformation of roads This approach involves continuously deforming shapes without cutting or pasting them, and considering them to be the same. A cup is roughly equivalent to a donut; if deformed continuously, it will have the same structure. “変形し続ける空間”として読む理論 A new mathematical fo

Mathematical applications of architecture: The fusion of mathematics and architectural design
Architecture is not merely the construction of space, but a fusion of art and science. Mathematics, in particular, plays a crucial role in architectural design. By translating abstract mathematical concepts into spatial ideas and visual forms, innovative architecture that transcends conventional concepts of gravity and structure can be created. This article explores how mathematical theories such as chaos theory, topology, and higher-dimensional geometry are applied to archit

Algorithmic Information Theory
A theory that considers "how short a program can be used to represent a given piece of information." For example, let's compare the following two: A 111111111111111111111111111111 this is, "Repeat 1 30 times" It can be explained briefly as follows: In other words, the amount of information is small.
