Grounded synthesis for “Stochastic calculus & Black-Scholes”
In Probability Theory, Stochastic Calculus, Martingales & Mathematical Statistics [1], Kolmogorov Measure-Theoretic Probability carries a "Supported" verdict (Kolmogorov (1933)): Provides the universal mathematical foundation for probability theory, stochastic processes, and statistical inference — Replaced heuristic frequency concepts with rigorous real analysis and Lebesgue integration. [2] In Probability Theory, Stochastic Calculus, Martingales & Mathematical Statistics [1], Itô Stochastic Calculus & Diffusions carries a "Supported" verdict (Itô (1944, 1951)): Allows differentiation and integration of non-differentiable stochastic paths in physics and financial mathematics — The foundational calculus of continuous-time derivative pricing and Langevin physical diffusion. [3]
[T1] Kolmogorov's measure-theoretic axioms establish probability as a normalized measure space (Omega, F, P), providing a rigorous foundation for conditional expectations and stochastic processes. [1] [4] [T1] Every continuous global symmetry of the action integral of a physical system yields a conserved current and associated time-invariant charge (Noether's First Theorem). [5] [6] [T1] The Riemann curvature tensor uniquely characterizes the intrinsic curvature of a pseudo-Riemannian manifold and determines the geodesic deviation of test particles in General Relativity. [7] [8]
Calibrated baseline benchmark in Probability Theory, Stochastic Calculus, Martingales & Mathematical Statistics [1]: df(X_t) = f' dX_t + 1/2 f'' d[X,X]_t — Itô's Lemma incorporating non-vanishing quadratic variation in continuous-time stochastic differential equations (Itô, Proc Imp Acad Tokyo 1944).
