On the Leonardo Sequence via Pascal-Type Triangles

Journal of Mathematics
In this study, we discussed the Leonardo number sequence, which has been studied recently and caught more attention. We used Pascal and Hosoya-like triangles to make it easier to examine the basic properties of these numbers.

Inadvertent - Ars accidentalis [PDF]

, 2008
Even though art is the product of an intentional act of fabrication, the serendipitous spill of an ink or paint, the unforeseen slip of a pen or brush, sudden shake of a camera in the analog realm have the potential of generating an unconscious lead in ...

A New Generalization of Leonardo Sequences: Biperiodic Leonardo Sequence

Journal of Mathematics
In this study, we define a new type of number sequence called biperiodic Leonardo sequence by the recurrence relation Lena,b=aLen−1+Len−2+1 (for even n) and Lena,b=bLen−1+Len−2+1 (for odd n) with the initial conditions Le0a,b=Le1a,b=1.

Puzzling the 120-cell

, 2015
We introduce Quintessence: a family of burr puzzles based on the geometry and combinatorics of the 120-cell. We discuss the regular polytopes, their symmetries, the dodecahedron as an important special case, the three-sphere, and the quaternions. We then

Multiplicity of Closed Reeb Orbits on Prequantization Bundles

, 2017
We establish multiplicity results for geometrically distinct contractible closed Reeb orbits of non-degenerate contact forms on a broad class of prequantization bundles.
