Abstract
We prove local (in space and time) well-posedness for a mildly regularised version of the stochastic quantisation of the \(\hbox {Yukawa}_{{2}}\) Euclidean field theory with a self-interacting boson. Our regularised dynamic is still singular but avoids non-local divergences, allowing us to use a version of the Da Prato–Debussche argument (Da Prato and Debussche in Ann Probab 31(4):1900–1916, 2003. https://doi.org/10.1214/aop/1068646370). This model is a test case for a non-commutative probability framework for formulating the kind of singular SPDEs arising in the stochastic quantisation of field theories mixing both bosons and fermions.
我们证明了具有自相互作用玻色子的\(\hbox {Yukawa}_{{2}}\)欧几里得场论的随机量子化的温和正则版本的局部(在空间和时间上)适定性。我们的正则化动态仍然是奇异的,但避免了非局部发散,允许我们使用一个版本的Da Prato - Debussche论证(Da Prato and Debussche in Ann Probab 31(4): 1900-1916, 2003)。https://doi.org/10.1214/aop/1068646370)。该模型是一个非交换概率框架的测试案例,用于在混合玻色子和费米子的场论的随机量子化中形成奇异spde。
