Infinite matrix associated to sequences
Mamy Laingo Nomenjanahary Rakotoarison, Dimbiniaina Ratovilebamboavison, Fanja Rakotondrajao
In this paper, we study the Euler-Seidel matrices with coefficients and determine the associated Riordan matrix to a given matrix, if it does exist. Computation of the generating f…
Parity alternating permutations starting with an odd integer
Frether Getachew Kebede, Fanja Rakotondrajao
A Parity Alternating Permutation of the set is a permutation with even and odd entries alternatively. We deal with parity alternating permutations having…
The sets of flattened partitions with forbidden patterns
Olivia Nabawanda, Fanja Rakotondrajao
The study of pattern avoidance in permutations, and specifically in flattened partitions is an active area of current research. In this paper, we count the number of distinct flatt…
Run Distribution Over Flattened Partitions
O. Nabawanda, F. Rakotondrajao, A. S. Bamunoba
The study of flattened partitions is an active area of current research. In this paper, our study unexpectedly leads us to the OEIS numbers A124324. We provide a new combinatorial…
A state enumeration of the foil knot
Franck Ramaharo, Fanja Rakotondrajao
We split the crossings of the foil knot and enumerate the resulting states with a generating polynomial. Unexpectedly, the number of such states which consist of two components are…
