Euler?s Exponential Formula for Semigroups [PDF]
Semigroup Forum, 2004 The aim of this paper is to show that Euler’s exponential formula $\lim_{n\rightarrow\infty}\linebreak[4] (I-tA/n)^{-n}x = e^{tA}x$, well known for $C_0$ semigroups in a Banach space $X\ni x$, can be used for semigroups not of class $C_0$, the sense of the convergence being related to the regularity of the semigroup for $t>0$.

Which point sets admit a $k$-angulation?
Journal of Computational Geometry, 2014 For \(k\ge 3\), a \(k\)-angulation is a 2-connected plane graph in which every internal face is a \(k\)-gon. We say that a point set \(P\) admits a plane graph \(G\) if there is a straight-line drawing of \(G\) that maps \(V(G)\) onto \(P\) and has the ...

Degree formula for the Euler characteristic [PDF]
Proceedings of the American Mathematical Society, 2012 We give a proof of the degree formula for the Euler characteristic previously obtained by Kirill Zainoulline. The arguments used here are considerably simpler and allow us to remove all restrictions on the characteristic of the base field.

Sketching and Stacking With Random Fork Based Exact Signal Recovery Under Sample Corruption
IEEE Access, 2020 In this paper, we propose a new technique for exact recovery of missing data due to impulsive noise in time-domain sampled acoustic waves, named as sketching and stacking with random fork (SSRF).

UNUSUAL FORMULAE FOR THE EULER CHARACTERISTIC [PDF]
Journal of Knot Theory and Its Ramifications, 2002 Everyone knows that the Euler characteristic of a combinatorial manifold is given by the alternating sum of its numbers of simplices. It is shown that there are other linear combinations of the numbers of simplices which are combinatorial invariants, but that all such invariants are multiples of the Euler characteristic.

General Euler-Boole's and dual Euler-Boole's formulae [PDF]
Mathematical Inequalities & Applications, 2005 The aim of this talk is to give general Euler-Boole's and dual Euler-Boole's formulae. More precisely, we derive formulae of Boole type where the integral is approximated not only with the values of the function in certain points but also with values of its derivatives up to (2n-1)-th order in end points of the interval. Our method produces formulae of

Upper bounds on the bondage number of a graph
Electronic Journal of Graph Theory and Applications, 2018 The bondage number b(G) of a graph G is the smallest number of edges whose removal from G results in a graph with larger domination number. We obtain sufficient conditions for the validity of the inequality b(G) ≤ 2s − 2, provided G has degree s vertices.

On dual Euler-Simpson formulae
Bulletin of the Belgian Mathematical Society - Simon Stevin, 2001 The dual Euler-Simpson formulae are given. A number of inequalities, for functions whose derivatives are either functions of bounded variation or Lipschitzian functions or functions in L_p-spaces, are proved. The results are applied to obtain the error estimates for some quadrature rules.

, 2002 In q-calculus, the Jackson formula (19.2) provides a way to compute explicitly a q-antiderivative of any function. Recall that the Jackson formula was deduced formally using operators. We will do a similar thing for the h-antiderivative in this chapter.
