In type theory, a theory within mathematical logic, the bottom type of a type system is the type that is a subtype of all other types. Where such a type exists, it is often represented with the up tack (⊥) symbol. When the bottom type is empty, a function whose return type is bottom cannot return any value, not even the lone value of a unit type. In such a language, the bottom type may therefore be known as the zero or never type. In the Curry–Howard correspondence, an empty type corresponds to falsity. (Wikipedia).
What are the names of different types of polygons based on the number of sides
👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1

Colouring graphs with no odd holes - Paul Seymour
Paul Seymour Princeton University September 22, 2014 The chromatic number k(G)k(G) of a graph GG is always at least the size of its largest clique (denoted by w(G)w(G)), and there are graphs with w(G)=2w(G)=2 and k(G)k(G) arbitrarily large. On the other hand, the perfect graph theorem ass
