摘要:Chromosome structure is a very limited model of the genome including the information about its chromosomes such as their linear or circular organization, the order of genes on them, and the DNA strand encoding a gene. Gene lengths, nucleotide composition, and intergenic regions a...

摘要:Abstract(#br) Background(#br)One of the main aims of phylogenomics is the reconstruction of objects defined in the leaves along the whole phylogenetic tree to minimize the specified functional, which may also include the phylogenetic tree generation. Such objects can include nucl...

摘要:Abstract(#br)Using a modification of the invariant Jensen forcing of [11], we define a model of ZFC , in which, for a given n ≥ 3 , there exists a lightface Π n 1 -set of reals, which is a E 0 -equivalence class, hence a countable set, and which does not contain any OD eleme...

摘要:Abstract(#br)We make use of a finite support product of the Jensen minimal Π 2 1 singleton forcing to define a model in which Π 2 1 uniformization fails for a set with countable cross-sections. We also define appropriate submodels of the same model in which separation fails ...

摘要:Abstract(#br)The aim of this paper is to demonstrate that several non–rigorous methods of mathematical reasoning in the field of divergent series, mostly related to the Euler and Hutton transforms, may be developed in a correct and consistent way by methods of the grossone a...

摘要:Abstract(#br)In the early years of set theory, Du Bois Reymond introduced a vague notion of infinitary pantachie meant to symbolize an infinity bigger than the infinity of real numbers. Hausdorff reformulated this concept rigorously as a maximal chain (a linearly ordered subset) ...

摘要:A generic extension L [ x , y ] of the constructible universe L by reals x , y is defined, in which the union of E 0 ‐classes of x and y is a lightface Π 2 1 set, but neither of these two E 0 ‐classes is separately ordinal‐definable.

摘要:Abstract(#br)Following a research line suggested by Ilijas Farah, we prove that for any abelian Polish σ -compact group H there exists an F σ Radon–Nikodym ideal, that is, an ideal Z ⊆ P ( N ) together with a Borel Z -approximate homomorphism f ...

摘要:Abstract We modify the definable ultrapower construction of Kanovei and Shelah (2004) to develop a ZF -definable extension of the continuum with transfer provable using countable choice only, with an additional mild hypothesis on well-ordering implying properness. Under the same ...
