Context. Semi-regular variables (SRVs) are similar to Miras in brightness, and they also follow one or more period–luminosity relations (PLRs), though not necessarily the same as Miras. As potential standard candles challenging than because of their smaller variability amplitudes less regular light curves, but substantially numerous especially promising for probing old stellar populations. Aims...

In this paper first we introduce the notion of weak $Gamma$-(semi)hypergroups, next some classes of equivalence relations which are called good regular and strongly good regular relations are defined.  Then we investigate some properties of this kind of relations on weak $Gamma$-(semi)hypergroups.

We show that every semi-artinian module which is contained in a direct sum of finitely presented modules in $si[M]$, is weakly co-semisimple if and only if it is regular in $si[M]$. As a consequence, we observe that every semi-artinian ring is regular in the sense of von Neumann if and only if its simple modules are $FP$-injective.

The pipeline to get the semi-regular mesh of a specific physical object is long and fastidious : physical acquisition (creating a dense point cloud), cleaning/meshing (creating an irregular triangle mesh), and semi-regular remeshing. Moreover, these three stages are generally independent, and processed successively by different tools. To overcome this issue, we propose in this paper a new frame...

This paper explains how efficient support for semiregular distributions can be incorporated in a uniform compilation framework for hybrid applications. The key focus of this work is in showing how, unlike other existing schemes, our scheme is able to minimize preprocessing overheads and maintain sophisticated communication optimizations (such as reduction of inter-processor communication during...

— We give a new proof for microlocal resolvent estimates for semi-classical Schrödinger operators, extending the known results to potentials with local singularity and to those depending on a parameter. These results are applied to the study of the stationary Schödinger equation with the approach of semi-classical measures. Under some weak regularity assumptions, we prove that the stationary Sc...
