Properties of Euler Diagrams [PDF]

open access: yes, 2007
Euler diagrams have numerous application areas, with a large variety of languages based on them. In relation to software engineering, such areas encompass modelling and specification including from a formal perspective. In all of these application areas,

A Survey of Euler Diagrams [PDF]

open access: yes, 2014
Euler diagrams visually represent containment, inpresstersection and exclusion using closed curves. They first appeared several hundred years ago, however, there has been a resurgence in Euler diagram research in the twenty-first century.

Restricted sum formula of alternating Euler sums [PDF]

open access: yesThe Ramanujan Journal, 2014
In this paper we study restricted sum formulas involving alternating Euler sums which are defined by ζ(s_1,...,s_{d};ε_1,...,ε_d)=\sum_{n_1>...>n_d\ge 1}\frac{ε_1^{n_1}... ε_{d}^{n_d}}{n_1^{s_1}... n_d^{s_d}}, for all positive integers s_1,...,s_{d} and ε_1=\pm 1,..., ε_{d}=\pm 1 with (s_1,ε_1) unequal (1,1).

Alternating Euler $T$-sums and Euler $\tilde S$-sums

open access: yes, 2020
In this paper, we study the alternating Euler $T$-sums and related sums by using the method of contour integration. We establish the explicit formulas for all linear and quadratic Euler $T$-sums and related sums. Some interesting new consequences and illustrative examples are considered.

A Counterexample to Euler's Sum of Powers Conjecture [PDF]

open access: yesMathematics of Computation, 1967
Es handelt sich urn eine Vermutung Eulers, die Dickson im zweiten Band seiner Geschichte der Zahlentheorie auf Seite 682 sehr vorsichtig folgendermaßen ausdrückt: ``Euler expressed his belief that no sum of four fifth powers is a fifth power.'' Die Verff.

Euler Sums and Contour Integral Representations [PDF]

open access: yesExperimental Mathematics, 1998
This paper develops an approach to the evaluation of Euler sums involving harmonic numbers either linearly or nonlinearly. We give explicit formul{æ} for certain classes of Euler sums in terms of values of the Riemann zeta function at positive integers. The approach is based on simple contour integral representations and residue computations.

Embedding wellformed Euler diagrams [PDF]

open access: yes, 2008
Euler diagrams are collections of labelled closed curves. They are often used to represent information about the relationship between sets and, as such, they have numerous applications including: visualizing biological data, diagrammatic logics, and ...
