Summability methods

Resummation

In mathematics and theoretical physics, resummation is a procedure to obtain a finite result from a divergent sum (series) of functions. Resummation involves a definition of another (convergent) function in which the individual terms defining the original function are re-scaled, and an integral transformation of this new function to obtain the original function. Borel resummation is probably the most well-known example.The simplest method is an extension of a variational approach to higher order based on a paper by R.P. Feynman and H. Kleinert.In quantum mechanics it was extended to any order here, and in quantum field theory here.See also Chapters 16–20 in the textbook cited below. (Wikipedia).

The Importance of Atonement

The idea of ‘atonement’ sounds very old-fashioned and is deeply rooted in religious tradition. To atone means, in essence, to acknowledge one’s capacity for wrongness and one’s readiness for apology and desire for change. It’s a concept that every society needs at its center. For gifts and
