Après plusieurs années consacrées à la recherche en physique théorique, je concentre aujourd'hui mon énergie sur un nouveau projet : l'Académie du Marimba - une école dédiée à la transmission et à la préservation du patrimoine artistique congolais, à Kinshasa.
Apprendre, créer, réussir. 🇨🇩
Après quatorze ans à enseigner la musique ici, je rentre au pays.
Pas pour recommencer. Pour transmettre.
L'Académie du Marimba ouvre à Kinshasa en 2027- des instruments fabriqués sur place, en bois congolais, et des enfants d'ici qui jouent dessus.
Le travail continue. Il change simplement de sol.
L'Académie du Marimba n'est plus une idée. Une équipe de cinq fondateurs. Un programme structuré, du débutant au concertiste. Des instruments déjà construits, et bientôt fabriqués à Kinshasa, en padouk de chez nous. Derrière : quinze ans d'enseignement de la musique. Kinshasa, 2027. On construit sérieusement.
The real asset of CSG isn't a discovery, it's a discipline: strict separation of proved / imported / conjectural, then confirmed independently by a topological test. Modest, but rare. The framing is the contribution, not a new physical result.
What's new in CSG isn't a new entropy derivation, the log value was already known (Sen, Meissner). It's architectural: turning "we can't derive A/4" into a rigorous, labeled no-go theorem, showing the inaccessibility is a law of geometry, not a failure of method.

Bottom line on CSG: one result stands (under H), the no-go, Theorem SC. The horizon's spectral geometry fixes the log correction's order but cannot produce A/4; that term is imported from thermodynamics. Everything else is conditional or conjectural.
String theory assumes SUSY. LQG tunes the Immirzi parameter to land on A/4. In CSG I do something less glamorous: I label A/4 as imported, not derived. No theorem there, just a discipline. Proved / conditional / conjectural / imported. Honesty as method.
I didn't prove what the black-hole spectrum reveals. I proved what it provably cannot: the area term A/4 is out of reach of direct spectral counting (Theorem SC). One hypothesis, no quantization assumed. The negative result is the result.
Theorem SC is an invitation: attack it. A no-go, the area term A/4 provably can't come from direct spectral counting at order ℏ⁻¹·log(ℏ⁻¹). It rests on one hypothesis (H), no quantization scheme assumed. Find the crack, or it stands.
Can't resist: this series runs in powers of ¼, and a black hole's entropy is famously S = A/4. Pure coincidence, no numerology, I promise. But a fine excuse to ask where that 4 actually comes from. (Spoiler: thermodynamics, not the spectrum.)
Visualisation of the Geometric Series.✨✨✨✨
5/ In other words: the spectrum alone does not "contain" A/4. You can't read it off. A genuine no-go, not a technical gap. Many programs assume the opposite; CSG shows the spectral geometry forbids it.

What I love here: a picture handing you an exact result, no algebra. My CSG work leans on the same move, a geodesic action identity gives
S_γ = 4πM² = A/4, a black hole's entropy coefficient, straight from geometry.
I see the scientific community's reserve, and I think it's healthy. An unreviewed preprint from an independent researcher SHOULD be watched from a distance, with caution. That's the right instinct. I'm not asking for trust, I'm asking for verification.
We've known S = A/(4ℓ²_Pl) since Hawking.
What I establish is that the horizon carries its own signature : a logarithmic correction governed by topology, not by the ultraviolet:
S = A/(4ℓ²_Pl) + ½·log(A/ℓ²_Pl) + O(1).
A small term, but real pride: an independent researcher can hold a proof upright.
The open heart of CSG fits on one line:
[ω_micro] = M²·[ω_S²]
(Conj. 7.9)
equivalent to c₁(L_GF) = 1. Nobody has proven it, me included. Proving or refuting it changes the picture. Geometers welcome.
9/ …the full leading-term derivation via Toeplitz quantization rests on an OPEN conjecture (Conj. 7.9):
Vol(Π, ω_micro) = S_γ , i.e. [ω_micro] = M²·[ω_S²]
I label it honestly: open. Not proven.
2/ Start with the famous formula:
S = A / 4 (in Planck units)
A black hole's entropy scales with the AREA of its horizon, not its volume. One of the deepest results in physics. But where does that "1/4" actually come from?
10/ The status, no hedging:
✅ Proven (under H): Weyl law, constraint SC, log correction.
🟡 Conditional: area term via thermodynamic consistency.
🟠 Conjectural: leading term (Conj. 7.9).
CSG constrains other theories (LQG, strings), it does not refute them.

8/ The sharpest geometric result supporting the leading term, with no conjecture, is a geodesic action identity:
S_γ = ∮_γ ξ·dx = 4πM² = A/4
The loop closes geometrically. But…

7/ What the spectrum really gives (unconditionally, under H): the logarithmic correction to the entropy, topological in nature, "protected." In CSG's hierarchy this log is more fundamental than the area term. (Its exact coefficient is still debated.)

6/ So where does the 1/4 come from?
Not from spectral counting, but from THERMODYNAMIC CONSISTENCY: the first law + modular temperature force 1/4 (cancellation of the surface gravity κ). Area enters as a consistency condition, not as a spectral output.
