Cohomology of real permutohedral varieties |

| 초록본문(Abstract) | This talk focuses on the cohomology ring of real permutohedral varieties. Henderson computed its additive structure in 2012, showing that each generator in the $k$th cohomology group of an $n$-dimensional real permutohedral varieties corresponds to an alternating permutation formed by selecting $2k$ elements from $[n+1]$. Our main objective is to give an explicit description of the multiplicative structure in terms of alternating permutations. |
