چکیده
Abstract Let $${\mathfrak {X}}$$ X be a group class. A G is an opponent of if it not -group, but all its proper subgroups belong to . Of course, every cohopfian and the aim this paper describe smallest class containing admitting no such kind groups.

A Constructive Approach to “Universals”
But it is beyond the power of human capacity to frame and retain distinct ideas of all the particular things we meet with: every bird and beast men saw; every tree and plant that affected the senses, could not find a place in the most capacious understanding. During the Middle Ages, much of the debate about universals concerned the question whether or not they could be considered to " exist ". ...
متن کاملConstructive Type Classes in Isabelle
We reconsider the well-known concept of Haskell-style type classes within the logical framework of Isabelle. So far, axiomatic type classes in Isabelle merely account for the logical aspect as predicates over types, while the operational part is only a convention based on raw overloading. Our more elaborate approach to constructive type classes provides a seamless integration with Isabelle loca...
متن کاملA Unified Approach to Sequential Constructive Methods
A general treatment of a particular class of learning techniques for neural networks, called sequential constructive methods, is proposed. They subsequently add units to the hidden layer until all the input-output relations contained in a given training set are satisfied. Every addition involves the update of a small portion of the whole weight matrix and depends on a subset of samples whose si...
متن کاملA Constructive Approach to Noether's Problem
A general method is developed to attack Noether's Problem constructively by trying to nd minimal bases consisting of rational invariants which are quotients of polynomi-als of small degrees. The applications show that this approach is successful for many small groups and for most of the classical groups with their natural representations. AArmative answers to Noether's Problem are obtained for ...
متن کاملA constructive approach to triangular trigonometric patches
We construct a constrained trivariate extension of the univariate normalized B-basis of the vector space of trigonometric polynomials of arbitrary (finite) order n ∈ N defined on any compact interval [0, α], where α ∈ (0, π). Our triangular extension is a normalized linearly independent constrained trivariate trigonometric function system of dimension δn = 3n (n+ 1) + 1 that spans the same vect...
