An Ingenious Proof Strategy

Physics Research Institute.

In the director's office, Lu Zhou and Senior Brother Luo stood side by side before a blackboard. Staring at the few hastily scrawled lines of equations on it, they shared a tacit silence for over ten minutes.

About another five minutes passed.

Luo Wenxuan suddenly broke the silence.

"Can I go get some wine?"

"Wine?"

"It's a habit of mine. Whenever I run into a problem I can't figure out, I go find something to drink."

Lu Zhou asked, "What did you think of?"

"A paper in the annals-of-mathematics, from the 1974 edition... I can't remember which page. Witten had me read it back then." After thinking carefully for a while, Luo Wenxuan continued, "It mentioned a possible approach."

The annals-of-mathematics was Mathematical Annals. As one of the four top journals, the articles published there carried considerable authority.

Lu Zhou handed him the chalk and made an inviting gesture.

Luo Wenxuan did not stand on ceremony. He stood before the blackboard and pondered for a moment, lightly tossing the chalk in his hand before stepping forward and writing.

[The simplest case of energy density with standard order is λφ^4φ2, where 0＜λ<1...]

At this point, Luo Wenxuan paused and looked back at Lu Zhou.

"The existence and uniqueness of this field have already been proven. I can dig out that paper for you later."

"Okay." Lu Zhou nodded. "Go on."

Luo Wenxuan turned back around and continued speaking as he
