From generalized Tamari intervals to non-separable planar maps [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 Let v be a grid path made of north and east steps. The lattice TAM(v), based on all grid paths weakly above the grid path v sharing the same endpoints as v, was introduced by Pre ́ville-Ratelle and Viennot (2014) and corresponds to the usual Tamari ...

Ectopic A-lattice seams destabilize microtubules [PDF]
, 2014 Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

Exploring Structural Characteristics of Lattices in Real World
Complexity, 2020 There are two important models for data analysis and knowledge system: data cube lattices and concept lattices. They both essentially have lattice structures, which are actually irregular in our real world.

On the analytical continuation of lattice Liouville theory
Journal of High Energy Physics, 2023 The path integral of Liouville theory is well understood only when the central charge c ∈ [25, ∞). Here, we study the analytical continuation the lattice Liouville path integral to generic values of c, with a particular focus on the vicinity of c ...

Enumerating 2D and 3D lattice paths with arbitrary steps [PDF]
Mathematica BohemicaLet $S$ be a finite set of integer vectors. We consider lattice paths that use only the vectors in $S$. We focus on paths that use a fixed number of vectors. We generally assume vectors in $S$ have a fixed coordinate sum, which allows us to determine the

Component-by-component construction of good intermediate-rank lattice rules [PDF]
, 2003 It is known that the generating vector of a rank-1 lattice rule can be constructed component-by-component to achieve strong tractability error bounds in both weighted Korobov spaces and weighted Sobolev spaces.
