A note on the recursive computation of the bracket polynomial for closed 4-tangles

Franck Ramaharo

Given a 4-tangle shadow, we concatenate it with itself n times and form a knot by applying a closure operation that connects each top endpoint to the corresponding bottom endpoint…

The bracket polynomial of the Celtic link shadow

Franck Ramaharo

We derive the Kauffman bracket polynomial for the shadow of the Celtic link using two complementary approaches. The first approach uses a recursive relation within the…

Determinants of renewable energy consumption in Madagascar: Evidence from feature selection algorithms

Franck Ramaharo, Fitiavana Randriamifidy

The aim of this note is to identify the factors influencing renewable energy consumption in Madagascar. We tested 12 features covering macroeconomic, financial, social, and environ…

Nowcasting Madagascar's real GDP using machine learning algorithms

Franck Ramaharo, Gerzhino Rasolofomanana

We investigate the predictive power of different machine learning algorithms to nowcast Madagascar's gross domestic product (GDP). We trained popular regression models, including l…

A bracket polynomial for 2-tangle shadows

Franck Ramaharo

We compute the Kauffman bracket polynomial of the numerator and denominator closures of A + A + ... + A ( A is repeated n times), where A is a 2-tangle shadow that has at most 4 cr…

Note on sequences A123192, A137396 and A300453

Franck Ramaharo

We give the connection between three polynomials that generate triangles in The On-Line Encyclopedia of Integer Sequences (A123192, A137396 and A300453). We show that they are rela…
