1612.07648	i	in 1963 g. grtzer and e.t . schmidt proved that every algebraic lattice is isomorphic to the congruence lattice of some algebra ( @xcite ) . since the algebras constructed by them were infinite , the result immediately raised the question : does every finite lattice occur as the congruence lattice of a _ finite _ algeb...	the congruence lattices of all algebras defined on a fixed finite set ordered by inclusion form a finite atomistic lattice . each meet - irreducible element of being determined by a single unary mapping on , we characterize completely those which are determined by a permutation or by an acyclic mapping on the set . usi...	the congruence lattices of all algebras defined on a fixed finite set ordered by inclusion form a finite atomistic lattice . we describe the atoms and coatoms . each meet - irreducible element of being determined by a single unary mapping on , we characterize completely those which are determined by a permutation or by...
1608.06418	i	we presented here the results of a rigorous rr lyrae search in the corot archive . we found nine rrab stars in the data base that have not been studied and seven of them are new discoveries . three stars show the blazhko effect . the cycle - to - cycle variation of these blazhko effects are evident either for amplitude...	seven of them are new discoveries . the harmonic amplitude and phase declines with the harmonic order were studied for non - blazhko stars . we discovered significant random period fluctuation for one of the two oversampled target , cm ori . after a successful transformation of the corot band parameters to the johnson...	the corot satellite supplied the scientific community with a huge data base of variable stars . among them the rr lyrae stars have intensively been discussed in numerous papers in the last few years , but the latest runs have not been checked to find rr lyrae stars up to now . our main goal was to fill this gap and com...
1012.0039	c	studying the physics in the outer regions of clusters is very important to understand how clusters are formed , how the the intracluster gas is heated , as well as to constrain the formation of large - scale structure . because of the very low density in cluster outer regions , the collisional timescales are very long ...	we have studied systematically the effects of non - equilibrium ionization for relaxed clusters in thecdm cosmology using one - dimensional hydrodynamic simulations . we found that non - equilibrium ionization effects do not depend on cluster mass but depend strongly on redshift which can be understood by self - simila...	the densities in the outer regions of clusters of galaxies are very low , and the collisional timescales are very long . as a result , heavy elements will be under - ionized after they have passed through the accretion shock . we have studied systematically the effects of non - equilibrium ionization for relaxed cluste...
