    <title>Phylogenetic Tree Reconstruction via the Latent Framework</title>
    <link>https://thalens.org/papers/bio_phylogenetics/</link>
    <guid>https://thalens.org/papers/bio_phylogenetics/</guid>
    <description>Phylogenetic inference turns molecular sequences into historical relationships. Classical likelihood-based methods excel in practice, yet the information geometry of alignment data relative to tree topology is rarely summarized in coordinates comparable across studies.</description>

    <title>Dimension-Independent Finiteness of Central Configurations for Positive Masses</title>
    <link>https://thalens.org/papers/phy_smale6/</link>
    <guid>https://thalens.org/papers/phy_smale6/</guid>
    <description>We prove that for any $N \geq 3$ bodies with positive masses in $\mathbb{R}^d$ ($d \geq 2$), the number of central configurations modulo similarity is finite, resolving Smale&#x27;s 6th Problem in **every spatial dimension $d \geq 2$ simultaneously**.</description>

    <guid>https://thalens.org/papers/ml_structured_latent_basis/</guid>
    <description>We introduce the Structured Latent Basis (SLB) framework, a perspective on supervised learning that unifies feature engineering and modeling as a single problem: selecting a mathematical basis in which the target function is linear.</description>

    <description>The Z₃ Ansatz $\sqrt{m_r} = a(1 + b\cos(\theta_0 + 2\pi r/3))$ with $b^2 = 2$ is a parametrization — not a dynamical model — that encodes the Koide mass relation $Q = 2/3$.</description>

    <guid>https://thalens.org/papers/pde_tensor_algebra/</guid>
    <description>We introduce the **PDE Tensor Algebra**, a framework that represents any PDE system as a triple $(D, C, P)$ of tensors encoding dissipation, nonlinear coupling, and geometric constraints. The decomposition converts qualitative PDE questions — existence, uniqueness, regularity, stability — into computable algebraic conditions on the tensors.</description>

    <description>The Birch and Swinnerton-Dyer conjecture predicts that for an elliptic curve $E/\mathbb{Q}$ the Mordell-Weil rank equals the order of vanishing of the Hasse-Weil $L$-function at $s = 1$, and that the leading Taylor coefficient is expressed by an expl</description>

    <description>We present formal proofs of six foundational theorems in integer arithmetic: commutativity of addition and multiplication over ℤ, absorption of zero under multiplication, non-negativity of squared differences, and the dichotomy that every natural number is either zero or positive. All results are machine-verified in the Lean 4 proof assistant.</description>

    <guid>https://thalens.org/papers/nt_collatz_cycle_elimination/</guid>
    <description>We develop a systematic method for eliminating non-trivial cycles of the Collatz map $T(n) = n/2$ if $n$ is even, $T(n) = 3n+1$ if $n$ is odd, and complement it with a stopping time analysis toward the full conjecture.</description>

    <description>We derive the Kolmogorov energy spectrum $E(k) \sim \varepsilon^{2/3} k^{-5/3}$ and anomalous intermittency corrections to the structure function exponents $\zeta_p$ from the Grade Equation — a universal structural decomposition theorem for analytic dynamical systems. The derivation proceeds in three steps.</description>

    <description>We formalize financial contagion as a Grade-2 hazard model on networks and show how the cascade threshold is tied, under explicit spectral proportionalities, to a concentration index: the Latent Number $\rho$ of the interbank network.</description>

    <title>Spectral Pricing: Bayesian Learning and the Explore-Exploit Frontier via the Latent Framework</title>
    <link>https://thalens.org/papers/econ_latent_dynamic_pricing/</link>
    <guid>https://thalens.org/papers/econ_latent_dynamic_pricing/</guid>
    <description>A seller facing unknown demand must balance exploration (learning the demand curve) against exploitation (maximizing immediate revenue). We organize the explore-exploit tradeoff through the Latent Number $\rho$ of the demand function.</description>

    <title>When Does Heterogeneity Matter? A Spectral Theory of Wealth Distribution and General Equilibrium</title>
    <link>https://thalens.org/papers/econ_latent_heterogeneous_agents/</link>
    <guid>https://thalens.org/papers/econ_latent_heterogeneous_agents/</guid>
    <description>Heterogeneous agent models (Aiyagari, 1994; Bewley, 1986) have become the workhorse of quantitative macroeconomics, but their computational demands are severe: the state variable is the entire wealth distribution — an infinite-dimensional object.</description>

    <title>Latent Mechanism Design: Spectral Approximation of Optimal Mechanisms</title>
    <link>https://thalens.org/papers/econ_latent_mechanism_design/</link>
    <guid>https://thalens.org/papers/econ_latent_mechanism_design/</guid>
    <description>We apply the Latent spectral framework to mechanism design, framing bilateral-trade tensions through a spectral parameter $\rho$ (Latent Number) of the type distribution.</description>

    <title>Spectral Microstructure: Kyle&#x27;s Lambda, Price Discovery, and the HFT Debate through the Latent Lens</title>
    <link>https://thalens.org/papers/econ_latent_microstructure/</link>
    <guid>https://thalens.org/papers/econ_latent_microstructure/</guid>
    <description>We recast Kyle&#x27;s (1985) insider-trading and price-discovery story in the Latent spectral framework: price impact $\lambda$, spreads, and depth are read through the Latent Number $\rho$ of the price signal.</description>

    <title>Spectral Taxation: The Latent Structure of Optimal Income Tax Schedules</title>
    <link>https://thalens.org/papers/econ_latent_optimal_taxation/</link>
    <guid>https://thalens.org/papers/econ_latent_optimal_taxation/</guid>
    <description>We apply the Latent spectral framework to the Mirrlees (1971) optimal taxation problem, showing that the information rent, tax schedule complexity, and welfare cost of progressive taxation are all governed by the Latent Number $\rho$ of the ability distribution.</description>

    <description>Arrow&#x27;s Impossibility Theorem (1951) proves that no social welfare function over three or more alternatives can simultaneously satisfy Unanimity, Independence of Irrelevant Alternatives (IIA), and Non-Dictatorship.</description>
