Open problems for equienergetic graphs
The energy of a graph is equal to the sum of the absolute values of its eigenvalues. Two graphs of the same order are said to be equienergetic if their energies are equal. We point out the following two open problems for equienergetic graphs. (1) Although it is known that there are numerous pairs of equienergetic, non-cospectral trees, it is not known how to systematically construct any such pa...
متن کاملOpen standards, open formats, and open source
The paper proposes some comments and reflections on the notion of “openness” and on how it relates to three important topics: open standards, open formats, and open source. Often, these terms are considered equivalent and/or mutually implicated: “open source is the only way to enforce and exploit open standards”. This position is misleading, as it increases the confusion about this complex and ...
متن کاملOpen Access, Open Science, Open Society
Open Access’ main goal is not the subversion of publishers’ role as driving actors in an oligopolistic market characterized by reduced competition and higher prices. OA’s main function is to be found somewhere else, namely in the ability to subvert the power to control science’s governance and its future directions (Open Science), a power that is more often found within the academic institution...
متن کاملOn weakly eR-open functions
The main goal of this paper is to introduce and study a new class of function via the notions of $e$-$theta$-open sets and $e$-$theta$-closure operator which are defined by Özkoç and Aslım [10] called weakly $eR$-open functions and $e$-$theta$-open functions. Moreover, we investigate not only some of their basic properties but also their relationships with other types of already existing topolo...
متن کاملOpen. Closed. Open
As a window into the subject, we recount some of the history (and geography) of two mature, challenging, partially open, partially closed problems in the theory of rewriting (numbers 13 and 21 from the original RTA List of Open Problems). One problem deals with (criteria for left-linear) confluence and the other with termination (of one linear or string rule), the two paradigmatic properties of...
