Outline of Research at the Start

本研究では,非線形確率偏微分方程式(SPDE)を解析するための道具であるHairer氏の理論とGubinelli氏らの理論の双方の利点を生かし,より一般のSPDEの解析を行う.SPDEは特に統計物理の分野などでランダム性を含む現象を表すモデルとして広く使われているが,近年はHairer氏らのアプローチにより目覚ましく発展している.本研究では具体的なSPDEを足がかりに2つの理論を発展させ,その難点を克服する新しいアプローチを生み出すことを目標とする.

Outline of Final Research Achievements

We studied stochastic partial differential equations with renormalizations both theoretically and practically. Theoretically, we proved that the two approaches, the theory of regularity structures, which is based on a local analysis, and the theory of paracontrolled calculus, which is based on Fourier analysis, are equivalent in a sense. Practically, we proved renormalizability and local or global in time solvability of several stochastic partial differential equations important in mathematical physics, such as the stochastic quantization associated with the Hoegh-Krohn model, nonlinear damped stochastic wave equations, and quasilinear parabolic equations with general nonlinear terms.

Academic Significance and Societal Importance of the Research Achievements

近年,繰り込みという特別な操作が必要な確率偏微分方程式が注目を集めており,場の量子論などの観点から盛んに研究されている.本研究課題の第一の成果は,この分野における正則性構造理論とパラ制御解析という2つの異なるアプローチが本質的に同値であることを厳密に示したことである.また第二の成果は,Hoegh-Krohnモデルなどの重要なモデルの繰り込み可能性を,場合によって一般論を拡張しながら証明したことである.これらの成果により,繰り込みを伴う確率偏微分方程式の一般論としての研究がさらなる発展を遂げることが期待される.
