Before explaining the obtained results in details we start a summary on the intellectual merits and
broader impact of the project.
The PI initiates a new approach (in items 2,5, 6), using the precise large time
asymptotic behavior of solutions of a parabolic equation to study the geometric property of K
manifolds, and to solve the Poincar Lelong equation. The method is effective in proving
sharp and optimal result. The method reminisces the celebrated ergodic theorem of Birkhoff
which connects the space average of a continuous function on the phase
space of a Hamiltonian system with its time average taking along the trajectory (see the second part for
detailed descriptions). This connection is also in some way related to other

In item
11 comparison result for viscosity solutions of some first and second order PDEs are proved. This
immediately yields the celebrated Levy-Gromov isoperimetric inequality and its generalization
as consequences. In item 14, a classification result on four dimensional gradient shrinking
solitons with nonnegative isotropic curvature was proved. This result generalizes the earlier result of
Naber, which proves a classification under the stronger assumption of bounded nonnegative
curvature operator.
The research conducted in items 2, 3, 4, 5, 6 are related to Birkhoff ergodic
theorem (which was applied by H. Weyl to understand the retreats and advances of glaciers. Further
understanding of this connection shall be sensational to the subject of partial differential equation and
dynamic system. The research in items 9, 12, 13 are related to the concept of entropy in
thermodynamics, which have impacts to other sciences beyond mathematics. The work in item 1
contributes an advancement in the high energy physics.
In promoting teaching, training, and learning, the PI
advised (including some current students) nine Ph.D students, including two female graduate
students, and served/serves as the faculty mentor for several postdoc visitors, including one SEW
assistant professor at UC San Diego. At UC San Diego the PI teaches the courses
This paper forms 60% of the assessment in this course. This paper may be retained by the candidate.
This milestone, which covers Sections I and II of Final Project Part II, is a paper structured as follows:
Chapter 2 leads the reader to an extensive and comprehensive research to find the appropriate answer for the stated problem before. The reasons and proofs are provided to support the justification.
It can also be shown that the sensitivities satisfy the following recurrence relation in equation 3.12
Read ONLY the introductory paragraph of this paper. Then answer the following questions about the introduction:
The given theme has been investigated by us for two years. Thus from abstract work it has developed into scientific research to what the volume of the material we provide testifies.
What are some conclusions made by the authors about the application of this framework in this case? (1 points)
Finally, another major improvement that is conditioned on the subject property is the new proposed

This thesis is separated into two main sections, namely a theoretical part and a practical part.
The article has been written by Khalil, Cohen, and Schwartz. The main purpose of this paper is to make
Based on the above analysis we suggest that the solution provided by Coopers and Myers are
During the realization of the thesis questions arose that had to be solved in order to have a complete research. These unknowns were not contemplated from the beginning since it was not expected to have such results so it is now necessary to sustain and explain
