Motives for reflections. Part two
(2013-12-13)Facsimile of a manuscript from the archive of Emanuels Grinbergs, University of Latvia. The article (in three pieces of manuscripts), written in Russian, contains some reflections on graph theory. It may be written in ... -
Nonlinear Spectra: the Neumann Problem
(Vilnius Gediminas Technical University, 2009) -
Notes in the graph theory. A manuscript (with flower snark J5)
(2013-12-13)This fragment of manuscripts, written in Latvian, is taken from a hardcover notebook of E.Grinbergs. The date when these notes started 29.7.72 is clearly seen on the first page, on the page 7 the date is 31.8.72, on 10th ... -
On building 4-critical plane and projective plane multiwheels from odd wheels
(2013-01-31)We build unbounded classes of plane and projective plane multiwheels that are 4-critical that are received summing odd wheels as edge sums modulo two. These classes can be considered as ascending from a single common graph ... -

ON CYCLE INVARIANT
(2013-04-23)Taking the programming paradigm with the cycle invariant as a base notion there for a ground cycle paradigm, in a more general setting here these things are considered. Epistemological aspects with reference to Rene Descartes ... -
On Dirac magnetic monopole and Hopf fibration

On educational problems of mathematics for the faculty of economics and management
(2013-12-17)Problems concerning education of mathematics for the students of the Faculty of economics and managements are considered. -
On Grinbergs' differential geometry and finite fields
(2019-03-27)Emanuels Grinbergs, in his youth, during ten years, from 1933 until 1943, wrote three dissertations on one subject, namely, differential geometry [1, 2, 3]. We think that his work in this direction has been neglected for ... -
On Grinberg’s Criterion
(Universiteit Gent, Faculty of Science, 2019)We generalize Grinberg’s hamiltonicity criterion for planar graphs. To this end, we first prove a technical theorem for embedded graphs. As a special case of a corollary of this theorem we obtain Zaks’ extension of Grinberg’s ... -
On osculation, superosculation and characteristic points
(1943-04)Translated into English by D. Zeps Original text: Par oskulāciju, superoskulāciju un charakteristiskiem punktiem, https://dspace.lu.lv/dspace/handle/7/46435 Facsimile of the manuscript of dissertation: https://dspace ... -
On speeding up synthesis and prediction of functions
(Latvia State University, 1974) -
On the reducibility of function classes
(Latvia State University, 1972)N – the set of all natural numbers, F – the set of all total functions N→N, A, B<=F. We say that A is m-reducible to B (A<=m B), iff there is a recursive operator M such that f in A, iff M(f) in B for all f in F. Similarly, ... -
One more geodesic graph
(2013-12-17)In this note, written in Latvian, a way to build geodesic graphs, graphs with unique shortest path between every two vertices, is considered. Geodesic graphs are trees, odd cycles, and nontrivial example, the graph of ... -
Ornamental sign language in the first order tracery belts
(Prespacetime Journal, 2010)We consider an ornamental sign language of first order where principles of sieve displacement, of asymmetric building blocks as a base of ornament symmetry, color exchangeability and side equivalence principles work. Generic ... -
