| Outline of Final Research Achievements |
We considered decorated geometric crystals, which are deeply related to tropical
R-maps on geometric crystals.For types A,B,C,D and G, we obtained several results on the relations with monomial realizations of crystal bases.In particular, decoration functions of decorated geometric crystals are expressed as a sum of monomials with positive coefficients via generalized minors, which means that there exist certain interesting relations between monomial realizations and polyhedral realizations of crystal bases and these results are all new.
