- In mathematics, a Petrovsky lacuna, named for the Russian mathematician I. G. Petrovsky, is a region where the fundamental solution of a linear hyperbolic partial differential equation vanishes. They were studied by who found topological conditions for their existence. Petrovsky's work was generalized and updated by Atiyah, Bott, and Gårding . (en)
- 彼得羅夫斯基空白（Petrovsky lacuna）得名自俄羅斯數學家伊萬·格奧爾基耶維奇·彼得羅夫斯基，是一個線性雙曲線偏微分方程中，其為零的區域。 這是由Petrovsky （）提出，他找出了此區域存在的拓撲條件。 彼得羅夫斯基的研究後來已由Atiyah, Bott, and Gårding （, ）擴展及更新。 (zh)
