Combinatorics plays a prominent role in contemporary mathematics, due to the vibrant development it has experienced in the last two decades and its many interactions with other subjects. This book arises from the INdAM conference "CoMeTA 2013 - Combinatorial Methods in Topology and Algebra,'' which was held in Cortona in September 2013. The event brought together emerging and leading researchers at the crossroads of Combinatorics, Topology and Algebra, with a particular focus on new trends in subjects such as: hyperplane arrangements; discrete geometry and combinatorial topology; polytope theory and triangulations of manifolds; combinatorial algebraic geometry and commutative algebra; algebraic combinatorics; and combinatorial representation theory. The book is divided into two parts. The first expands on the topics discussed at the conference by providing additional background and explanations, while the second presents original contributions on new trends in the topics addressed by the conference.

Spesso i giochi danno lo spunto per affrontare argomenti matematici interessanti e significativi. Si tratta di un punto di partenza stimolante per accedere alla matematica, come gli autori hanno potuto verificare in occasione di molte lezioni-laboratorio tenute con studenti delle scuole superiori in Italia, Svizzera, Germania e Stati Uniti: da tale esperienza concreta nasce il presente volume. Insegnanti, studenti e appassionati di matematica troveranno nel libro percorsi che partono dai giochi e approdano a temi matematici talvolta fuori dagli schemi dei programmi scolastici: i grafi, le permutazioni, i gruppi, le funzioni di piu variabili reali, il teorema di punto fisso di Brouwer, gli omeomorfismi, le curve nel piano e i primi concetti della topologia, solo per citarne alcuni. Il testo si offre quindi sia come supporto pratico per proporre itinerari didattici, sia come lettura di approfondimento, che confidiamo piacevole, a proposito di alcuni giochi e della matematica che permettono di scoprire. Da tale esperienza concreta nasce il presente volume, che ne conserva la struttura di avvicinamento al rigore matematico attraverso domande e approfondimenti successivi, consolidati da molti esercizi.
