   Format: MarkdownItexWait a second. One does regularization, then renormalization. As far as I learned from Tamarkin's lectures, the resolutions correspond to the regularization (in fact standard regularization procedures can give resolutions). So, BV in this picture is about deformation quantization already. BV quantization is a quantization, why do you say now that it is classical picture only ? There must be a way to connect to Kantization recipe using the philosophy of BV integrals which are in path formalism.

   Format: MarkdownItexShouldn't we have also [[chiral algebra]] not only [[Chiral algebras]]. I mean chiral algebra is not the same as VOA (certain class of VOAs can be I guess obtained from equivariant genus zero chiral algebras) though they are parts of the same subject, so the entry shudl be eventually distinct from [[vertex algebra]] and [[vertex operator algebra]].
