Chapter 380

At 6:30, the playground had already lit up. The two of them ran 6 kilometers, stretched, relaxed their muscles, and then sat in the old position to rest.

Having already reached the sports field, Xu Qingzhou threw away all mathematical calculations and the like, sweating to relax his brain.

The playground was still lively.

Xu Qingzhou couldn't help but be surprised. It had already been almost three years, and this senior sister who was carrying the weight forward was actually still here.

"Cough~"

Just as Xu Qingzhou was sighing, a warning cough sounded in his ear. He turned his head and saw Song Yao staring at him unhappily.

Xu Qingzhou leaned back and leaned on the steps. "I was just sighing that time passes too fast. When we first saw this senior sister, we were both only freshmen."

"You'd better be." Song Yao hummed, secretly glanced at that senior sister, secretly exhaled, and looked down at her own chest. Hmm, it seems... it's already perfect.

Xu Qingzhou leaned lazily on the steps, looked at Song Yao's appearance, and blurted out: "Small is also cute."

"."

Dead silence in the air.

"Xu Qingzhou." Song Yao gazed at her boyfriend.

"I can explain."

Xu Qingzhou felt his back go cold.

Song Yao's voice almost popped out from between her teeth, "No need to explain, you should think more about where I will bury you now."

"."

Xu Qingzhou held his old waist all the way home.

"Teacher Song, my waist is going to be pinched broken by you."

"Deserve it, I won't pity you." Song Yao pouted.

Still "small is also cute." Where is she small!

Xu Qingzhou wore boxer shorts, holding change of clothes in one hand, supporting his waist with the other, and stood at the doorway saying: "You should put the focus on the word 'cute'."

"Shut up, don't disturb me!"

Song Yao stared, not wanting to discuss with this guy the problem of whether it's cute or not.

"Alright, alright... such a big temper, don't say I bullied you. As compensation, I'll give you a chance to take a shower with me now."

"."

Song Yao's Qilin arm was about to be unable to be suppressed.

On this side, sensing the situation was wrong, Xu Qingzhou slipped into the bathroom to take a shower.

In the living room, Song Yao took a deep breath, trying to calm herself down. Confirmed, this guy Xu Qingzhou really has some strange attributes.

Having a perverted boyfriend is too tiring.

Song Yao sighed, lowered her head to do her own things, and focused her attention on the computer screen in front of her. The thesis was already half written.

It was quite smooth. Although she was only a junior now, she had almost finished learning the content of the master's graduate stage.

All economic activities have laws. As long as you master the logic in them slightly, you can achieve your goal by changing the variables in a certain link.

Therefore, it was handy to write.

The sound of clicking typing rang out in the living room.

【One of the main purposes of small and micro enterprise financing is to meet the daily operating liquidity needs, but in the financing market, due to "ownership discrimination" and "scale discrimination," small and micro enterprises often cannot get enough funds and liquidity support.】

【This paper proposes Hypothesis 1 and Hypothesis 2】

【Hypothesis 1: The value-added tax credit refund policy can increase the abundance of enterprise liquidity, improve enterprise liquidity, and alleviate enterprise funding pressure.】

Xu Qingzhou came out after showering, and Song Yao went in.

In the living room, Xu Qingzhou threw the clothes in the dirty clothes basket into the washing machine and sat down to ponder the ideas of the evening.

Xu Qingzhou smiled, lowered his head to continue research, and according to the previous ideas, planned to deduce from certain properties of the Kakeya set. Specifically, it was to start from the directionality of the Kakeya set.

The Kakeya set contains unit line segments that can be rotated to any direction. This property makes the Kakeya set highly flexible and complex geometrically.

If used properly, by studying the geometric properties of the Kakeya set and its relationship with the Kakeya maximal function, one can explore the change laws and characteristics of the function in different directions.

Finally, one can use the bilinear method to change the estimation of local smoothness.

Twilight deepened, Xu Qingzhou leaned on the chair, couldn't help but nod slightly, solved easily.

He glanced at the computer screen.

00:31 AM.

Xu Qingzhou didn't continue, turned off the lights, and went to the bedroom to sleep. The ideas were already clear, but to truly calculate it, it would take at least half a month.

Er Miao swung its tail and leisurely patrolled its territory in the living room.

March 23rd.

Please... you... collect_(!)

Xu Qingzhou went to Professor Chu Jiangfeng's office. When he arrived, only Yang Yongze was in the office.

"Junior brother, you're here." Yang Yongze waved to greet him.

Xu Qingzhou asked with a smile: "How is the new topic?"

Professor Chu Jiangfeng and Yang Yongze's new topic, geometric structure and topological invariants.

These two things are two closely connected and charming branches in the field of mathematics, and have wide applications in theoretical physics, computer science, material science, and many other fields.

For such big topics, the cycle can reach three or four years.

"The topic application has just been sent up."

Yang Yongze poured a cup of tea for Xu Qingzhou and said: "Junior brother, we are currently short of people, do you have any thoughts of participating?"

Xu Qingzhou thanked him and said helplessly: "I still have to be busy getting my doctoral degree certificate first."

"I always forget that you haven't graduated yet."

Yang Yongze shook his head and said: "According to the teacher's meaning, recruit two more doctoral students to follow and share the work. I also recruit two master's graduate students here to do odd jobs."

"Accepted apprentices? Congratulations, Senior Brother Yang." Xu Qingzhou said with a smile.

Yang Yongze shrugged and said: "Actually, by comparison, I prefer to focus on research, but the teacher said that sooner or later I have to lead."

"Why, complaining again about letting you lead graduate students?"

Professor Chu Jiangfeng walked in holding a teacup.

"How dare I, just sighing with junior brother that I also have to start leading graduate students." Yang Yongze laughed dryly.

Professor Chu Jiangfeng sat down, looked at Xu Qingzhou, and asked: "Qingzhou, is your calculation going smoothly?"

"It's okay, if optimistic, the thesis can be finished in a month."

Xu Qingzhou said with a smile.

Professor Chu Jiangfeng nodded, twisting the teacup, and continued to ask: "And the result?"

"Currently still calculating, but... shouldn't disappoint everyone."

Professor Chu Jiangfeng nodded slightly, feeling reassured in his heart. It was already March, and there wasn't much time left for Xu Qingzhou. If he changed the topic, being busy might also produce a graduation thesis, but the effect would definitely be greatly reduced.

"Awesome, junior brother." On the side, Yang Yongze couldn't help but give a thumbs up.

The research on the local smoothness of Fourier integral operators has always been an important direction for studying the properties of operators in harmonic analysis.

It can be said to be a quite large topic, more than enough for a master's graduation.

If this Xu Xu Shidi Xu can successfully produce it, needless to say, it will definitely cause another sensation.

Suddenly feeling pressure, what's going on.
