Tight contact structures on some small Seifert fibered 3--manifolds
Paolo Ghiggini, Paolo Lisca, Andras I. Stipsicz
We classify tight contact structures on the small Seifert fibered 3--manifold M(-1; r_1, r_2, r_3) with r_i in (0,1) and r_1, r_2 \geq 1/2. The result is obtained by combining conv…
P-partitions and a multi-parameter Klyachko idempotent
Peter McNamara, Christophe Reutenauer
Because they play a role in our understanding of the symmetric group algebra, Lie idempotents have received considerable attention. The Klyachko idempotent has attracted interest f…
Twisted Alexander norms give lower bounds on the Thurston norm
Stefan Friedl, Taehee Kim
We introduce twisted Alexander norms of a compact connected orientable 3-manifold with first Betti number bigger than one generalizing norms of McMullen and Turaev. We show that tw…
Description of surfaces associated with Grassmannian sigma models on Minkowski space
A. M. Grundland, L. Snobl
We construct and investigate smooth orientable surfaces in su(N) algebras. The structural equations of surfaces associated with Grassmannian sigma models on Minkowski space are stu…
