Abduction of Generalizations

Theoria, 2012
Abduction of generalizations is the process in which explanatory hypotheses are formed for an observed, yet puzzling generalization such as ``pineapples taste sweet" or ``rainbows appear when the sun breaks through the rain". This phenomenon has received

Generalizations of Tucker-Fan-Shashkin lemmas [PDF]

, 2016
Tucker and Ky Fan's lemma are combinatorial analogs of the Borsuk-Ulam theorem (BUT). In 1996, Yu. A. Shashkin proved a version of Fan's lemma, which is a combinatorial analog of the odd mapping theorem (OMT).

Generalizations of Steffensen’s inequality via two-point Abel-Gontscharoff polynomial

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
Using two-point Abel-Gontscharoff interpolating polynomial some new generalizations of Steffensen’s inequality for n−convex functions are obtained and some Ostrowski-type inequalities related to obtained generalizations are given.

Matrix generalizations of integrable systems with Lax integro-differential representations

Karpatsʹkì Matematičnì Publìkacìï, 2013
We found matrix integro-differential Lax representations for Davey-Stewartson systems (DSI, DS-II, DS-III), (2+1)-dimensional generalizations of Chen-Lee-Liu equation and its higher symmetries.

A Model for Teaching Mathematical Argument at the Elementary Grades

Journal of Educational Research in Mathematics, 2020
Over years of collaborating with elementary-school teachers to research students' thinking about the "big ideas" of K-6 mathematics, particular attention was given to generalizations about the operations-addition, subtraction, multiplication, and ...

Generalizations of quasielliptic curves [PDF]

Épijournal de Géométrie Algébrique
We generalize the notion of quasielliptic curves, which have infinitesimal symmetries and exist only in characteristic two and three, to a remarkable hierarchy of regular curves having infinitesimal symmetries, defined in all characteristics and having ...

Generalized symplectic symmetric spaces [PDF]

, 2013
Bielavsky introduced and investigated the class of symmetric symplectic spaces, that is, symmetric spaces endowed with a symplectic form invariant with respect to symmetries.

Digital semicovering and digital quasicovering maps

Applied General Topology, 2023
In this paper we introduce notions of digital semicovering and digital quasicovering maps. We show that these are generalizations of digital covering maps and investigate their relations.

Hyperuniformity and its Generalizations

, 2016
Disordered many-particle hyperuniform systems are exotic amorphous states characterized by anomalous suppression of large-scale density fluctuations. Here we substantially broaden the hyperuniformity concept along four different directions. This includes

Generic uses of the English pronoun one and the Spanish pronoun uno in parliamentary debates

Russian Journal of Linguistics
Impersonal pronouns one in English and uno in Spanish are described in the literature as functionally similar, combining two meaning components: first-person orientation and generalization.
