Existence and Uniqueness Theorems for the Neutron Transport Equation [PDF]

open access: yesJournal of Mathematical Physics, 1963
In an attempt to understand the conditions under which the neutron transport equation has solutions, and the properties of those solutions, a number of existence and uniqueness theorems are proved. One finds that the properties of the solution are closely related to the boundedness of the source as well as to certain velocity-space integrals of the ...

Existence and Uniqueness Theorem for Uncertain Wave Equation [PDF]

open access: yesSymmetry, 2022
In the real world, the indeterminate phenomenon and determinate phenomenon are symmetric; however, the indeterminate phenomenon absolutely exists. Hence, the indeterminate dynamic phenomenon is studied in this paper by using uncertainty theory, where the indeterminate dynamic phenomenon is associated with the belief degree and called the uncertain ...
