The rank condition and strong rank conditions for Ore extensions
Karl Lorensen, Johan Öinert
Let be a ring, a ring endomorphism, and a -derivation. We establish that the Ore extension satisfies the rank condition if and only if d…
A Shubin pseudodifferential calculus on asymptotically conic manifolds
Thomas Krainer
We present a global pseudodifferential calculus on asymptotically conic manifolds that generalizes (anisotropic versions of) Shubin's classical global pseudodifferential calculus o…
A positional statistic for 1324-avoiding permutations
Juan B. Gil, Oscar A. Lopez, Michael D. Weiner
We consider the class of permutations of size that avoid the pattern 1324 and examine the subset of elements for which ,…
Pattern-avoiding stabilized-interval-free permutations
Daniel Birmajer, Juan B. Gil, Jordan O. Tirrell +1
In this paper, we study pattern avoidance for stabilized-interval-free (SIF) permutations. These permutations are contained in the set of indecomposable permutations and in the set…
Enumeration of symmetric arc diagrams
Juan B. Gil, Luis E. Lopez
We give recurrence relations for the enumeration of symmetric elements within four classes of arc diagrams corresponding to certain involutions and set partitions whose blocks cont…
Restricted Grassmannian permutations
Juan B. Gil, Jessica A. Tomasko
A permutation is called Grassmannian if it has at most one descent. In this paper, we investigate pattern avoidance and parity restrictions for such permutations. As our main resul…
