From the Reviews". .. inside of PFTB (Proofs from The e-book) is certainly a glimpse of mathematical heaven, the place smart insights and lovely principles mix in extraordinary and wonderful methods.

Combinatorial Algebraic Geometry: Levico Terme, Italy 2013, Editors: Sandra Di Rocco, Bernd Sturmfels

Combinatorics and Algebraic Geometry have loved a fruitful interaction because the 19th century. Classical interactions comprise invariant idea, theta services and enumerative geometry. the purpose of this quantity is to introduce fresh advancements in combinatorial algebraic geometry and to procedure algebraic geometry with a view in the direction of functions, reminiscent of tensor calculus and algebraic facts.

Finite Geometry and Combinatorial Applications

The projective and polar geometries that come up from a vector area over a finite box are really helpful within the building of combinatorial items, akin to latin squares, designs, codes and graphs. This booklet offers an advent to those geometries and their many functions to different parts of combinatorics.
