A Sturm-Liouville eigenvalue problem is called self-adjoint if du du PU- de 0, dar because then uL(u) – vL(u)]dx = 0 for any two functions u and v satisfying the boundary conditions. Let consider a = O and b= L. Show that if u ...

For the distance Laplacian eigenvalues, we have given an upper bound and then find a condition for which the smallest Gersgorin disc contains every distance Laplacian eigenvalue of the distance Laplacian matrix. These results give partial answers from some questions that are raised in [2]....
I, personally, have benefited a lot from many of the answers that the moderator posts. I also get frustrated by a lot of messages that I waste time reading, like for example those messages from people who want to learn how to use ABAQUS.. Or questions like: what is finite element ...
Anybody have any ideas on where this is coming from. I'm happy knowing ONE of the answers is correct and that only a factor of 2x separates me from truth, but I'd very much appreciate it if someone could tell me what one is the right one. I'm inclined to believe...
From this general template, by choosing the property P, the type of graph matrix, and the value k, we can obtain an amazing variety of concrete spectral problems, ranging from trivial to extremely challenging ones. The study of such extremal questions is crucial to graph theory, for they pro...
