On the other hand, the nonexistent field with one element, $\mathbb F_1$, presents itself as a ghost candidate for an absolute basis in Algebraic Geometry to perform the Deninger-Manin program, which aims at solving the classical Riemann Hypothesis. This book, which is the first of its kind in the $\mathbb F_1$-world, covers several areas in $\mathbb F_1$-theory, and is divided into four main parts - Combinatorial Theory, Homological Algebra, Algebraic Geometry and Absolute Arithmetic. Topics treated include the combinatorial theory and geometry behind $\mathbb F_1$, categorical foundations, the blend of different scheme theories over $\mathbb F_1$ which are presently available, motives and zeta functions, the Habiro topology, Witt vectors and total positivity, moduli operads, and at the end, even some arithmetic. Each chapter is carefully written by experts, and besides elaborating on known results, brand new results, open problems and conjectures are also met along the way. The diversity of the contents, together with the mystery surrounding the field with one element, should attract any mathematician, regardless of speciality. 606 $aCombinatorics & graph theory$2bicssc 606 $aCombinatorics$2msc 606 $aNumber theory$2msc 606 $aCommutative rings and algebras$2msc 606 $aAlgebraic geometry$2msc 615 07$aCombinatorics & graph theory 615 07$aCombinatorics 615 07$aNumber theory 615 07$aCommutative rings and algebras 615 07$aAlgebraic geometry 686 $a05-xx$a11-xx$a13-xx$a14-xx$2msc 701 $aThas$b Koen$f1977-$0726617 801 0$bch0018173 906 $aBOOK 912 $a9910153279503321 996 $aAbsolute Arithmetic and$92564511 997 $aUNINA
