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

Noter's Theorem
"The symmetry of natural laws gives rise to conservation laws." Symmetry is not about visual beauty, but a principle that determines what the world preserves. 対称性によって空間の安定が保存される The golden axis extending from the circular void at the top to the stage and the center of the audience seating is "the amount to be preserved". The surrounding balconies and radial acoustic ribs unfold symmetrically, and the movements, sounds, and lights of the audience all converge towards an unchan

Divergence Theorem
The amount of "flow" that is created and disappears within a given space is equal to the total amount of flow that enters and leaves the surface of that space. "What happens internally is reflected at the interface." 内部の「発散」が建築の外皮に現れる With the central stage as the "source" of emission, golden light and movement lines radiate from the floor to the audience, walls, and ceiling, finally exiting through vertical slits in the ceiling. The relationship where "the total amount produ

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

Borsk-Ulam theorem
There are always two points on Earth that are diametrically opposed to each other where the temperature and atmospheric pressure are the same. Even if the external form is asymmetrical, the antipodal points on either side of the center of the building share the same environmental conditions. 「形は異なっていても、正反対の場所が同じ状態になる」 Despite its asymmetrical shape, the hall offers the same experience at its antipodal points. The ends of the straight line passing through the golden central po

Exploring new perspectives on architecture based on continuity and topology.
Architecture can be viewed not merely as a physical "thing," but as a "continuous space" where boundaries blend together, surfaces transform, and space flows without interruption. This perspective transcends conventional architectural concepts and invites us into the world of mathematical architecture, incorporating mathematical structures and topology. This time, we will introduce a new perspective on architecture centered on continuity and topology, along with specific meth

The appeal and uses of ebooks that are nearing completion
As an ebook nears completion, anticipation grows, along with thoughts about its content and how it can be used. In particular, ebooks dealing with themes gaining attention in contemporary design fields, such as #Parametric Design, #Generative Art, and #Algorithmic Architecture, become valuable learning resources for students and creators. This article will introduce the appeal of an ebook nearing completion and offer practical ways to utilize it. What is the appeal of ebooks?
