Triangular Trimers on the Triangular Lattice: an Exact Solution [PDF]

open access: yesPhysical Review Letters, 1999
A model is presented consisting of triangular trimers on the triangular lattice. In analogy to the dimer problem, these particles cover the lattice completely without overlap.

On Triangular Multisets and Triangular Fuzzy Multisets [PDF]

open access: yesMathematics, 2022
The basic set operations between fuzzy sets are defined using the min and max functions; however, later on, new operators were introduced that used other functions, which, nevertheless, had similar properties to functions min and max. The resulting fuzzy

Evaluation of the Residence Time Distribution (RTD) for Flow in Ducts with Velocity Profile of Two Independent Variables [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2022
The correct information on RTD can help in system design and evaluation. The RTD corresponding to the velocity profile is known only for certain cases, where the velocity profile depends on one coordinate only.

Common Fixed Point Theorems in M-Fuzzy Cone Metric Spaces

open access: yesResults in Nonlinear Analysis, 2021
This work aims to generalize the Banach contraction theorem to M-fuzzy cone metric spaces. We construct generalized M-fuzzy cone contractive conditions for three self mappings with which they have a unique common fixed point.
