I can NOT get over this man’s hair on @buzzrtv Match Game ‘77. If you are this man or know him I feel I should ask you some questions

I've been beaten by the LAPD. I lived in Berkeley in the late 1960s and early 1970s. I've been tear gassed and watched police push people backwards off of highway overpasses. I knew and understood many Black Panthers.
I am sick and tired of Kumbaya songs. I am sick and tired of turn-the-other-cheek reactions to current affairs in the US.
But I am also a lawyer, sworn to peaceful methods.
What do I do?
What strikes me is the age old method of ostracism - prac…

On fundamental properties of high-order forward-backward envelope

Abstract: This paper studies the fundamental properties of the high-order forward-backward splitting mapping (HiFBS) and its associated forward-backward envelope (HiFBE) through the lens of high-order regularization for nonconvex composite functions. Specifically, we (i) establish the boundedness and uniform boundedness of HiFBS, along with the H\"older and Lipschitz continuity of HiFBE; (ii) derive an explicit form for the subdifferentials of HiFBE; and (iii) investigate necessary and sufficient conditions for the differentiability and weak smoothness of HiFBE under suitable assumptions. By leveraging the prox-regularity of $g$ and the concept of $p$-calmness, we further demonstrate the local single-valuedness and continuity of HiFBS, which in turn guarantee the differentiability of HiFBE in neighborhoods of calm points. This paves the way for the development of gradient-based algorithms tailored to nonconvex composite optimization problems.
