Machine-Verified Proofs
Papers with Lean 4 formal verification
Papers whose central claims have been formalized and checked in Lean 4. These are the highest trust-level items in the corpus — the math has been re-verified by a proof assistant, not just reviewed by humans.

The Latent: Finite Sufficient Representations of Smooth Systems
We define the **Latent** of a smooth system as the basis-free element of a graded Hilbert tensor algebra that completely characterizes the system's distributional, dynamic, and functional properties.

The Projected-Generator Method for Path-Dependent Derivative Pricing
Derivative pricing has a clear mathematical target: compute the discounted
risk-neutral value of a payoff under a specified model. For European vanilla
contracts this target is often analytic or nearly analytic.

Toward the Riemann Hypothesis: A Superquadratic-Growth Framework for Zeta Moments and its Limits
We present an algebraic framework relating the growth of the zeta
moments to Hankel-determinant structure, together with an honest
account of where the framework does and does not reach the Riemann
Hypothesis.

Resolving the Equity Premium Requires at Least Two Dimensions: A Machine-Checked Class No-Go and a Term-Structure Discriminator
The equity premium puzzle of Mehra and Prescott (1985) is the observation that the
standard consumption-based asset pricing model, calibrated to plausible risk
aversion and the observed smoothness of aggregate consumption, predicts an equity
premium

The Yang-Mills Mass Gap via Gauge Absorption and Perelman W-Entropy
**Theorem A (Main result, conditional).** Conditional on the 20 named Tier A–D hypotheses of §7.1 — in particular the three Tier-D perturbative-QFT inputs (`tomboulis_formula`, `b_zero_from_feynman`, `beta_1_rge_def`) — we establish that Yang-Mills t

When In-Context Learning Implements Gradient Descent: A Learned Mechanism, Mechanically Verified and Empirically Tested
We turn the gradient-descent account of in-context learning (ICL) into machine-checked mathematics and falsifiable predictions about real transformers. The formal target is the linear-attention regression identity: a forward pass can implement one gradient-descent step on an implicit least-squares objective.

Contaminated by Construction: Separating Simulation Noise from Model Risk in ES Backtests
Expected Shortfall backtesting under Basel III/IV suffers from an unmeasured structural weakness: Monte Carlo estimation of ES injects computational noise into the Acerbi-Székely (2014) test statistic, but the magnitude of this contamination has not

The Latent of Latents: Hierarchical Finite Representations of Knowledge Families
The Latent Theorem guarantees that any smooth system has a finite representation whose size depends on regularity and accuracy, not on ambient dimensionality. We extend this result to **families** of smooth systems.

Deterministic Portfolio VaR Without Monte Carlo: The Eigen-COS Method
We present the Eigen-COS method, a deterministic algorithm that computes exact Value-at-Risk, closed-form Expected Shortfall, and the full CDF/PDF for weighted sums of correlated lognormal assets — without Monte Carlo simulation.

The Spectral Lognormal Distribution
The CDF of a weighted sum of correlated lognormal random variables has lacked a tractable characterization since Fenton (1960). We show that eigenvalue conditioning of the correlation matrix, followed by Fourier-cosine inversion, yields an analytic, grid-free $N$-term spectral representation of that CDF: the **Spectral Lognormal Distribution**.

What Is a Return? (Especially When Prices Can Be Negative)
Every formula in quantitative finance — CAPM, Markowitz, VaR, Sharpe ratio, GARCH — takes returns as input. Yet the standard definitions of return fail when prices cross zero: log-returns are undefined, and simple returns produce sign errors.

Terminal Portfolio Value Distribution to Machine Precision
We present a deterministic, semi-analytical framework for computing the complete distribution of a portfolio's terminal value at horizon $T$ for correlated lognormal assets. Unlike traditional approaches, this method requires no Monte Carlo simulation.

Capacity, Scaling, and Grokking from the In-Context Learning = Gradient Descent Mechanism
The companion core paper establishes, and machine-checks, a single identity: a transformer's forward pass can implement one gradient-descent step on an implicit least-squares objective (the ICL=GD mechanism). This satellite asks what that verified identity forces to be true about *representational capacity and scaling*.

An Unconditional BGST$\to$R$_2$ Fourier Transfer via Poisson-Kernel Deconvolution
Baluyot, Goldston, Suriajaya, and Turnage-Butterbaugh [BGST23] proved the first unconditional asymptotic for Montgomery's pair-correlation function $F(\alpha, T)$, with error $O(1/\sqrt{\log T})$ uniformly for $\alpha \in [0,1]$.
