Some challenging problems on numerical semigroups
 
 
Description:  A numerical semigroup is just a co-finite submonoid of the nonnegative integers, under addition. Despite being so simple mathematical objects, they hide very challenging combinatorial and computational problems (among others, coming from various areas of mathematics). The aim of the seminar is to introduce the numerical semigroups (I plan to do it with the help of the GAP packages 'numericalsgps' and 'intpic'), and refer some of the challenges that captured my attention in the recent past.
