The number of isomorphism classes of spreads
Topology and its Applications, 1990 AbstractRoughly, a spread is a “continuous” collection of generalized chords. We simultaneously prove conjectures of Grünbaum by finding c (the cardinality of the continuum) many pairwise nonisomorphic spreads such that for every two of them every finite part of one is isomorphic to a finite part of the other.

Isomorphism classes of bipartite cycle permutation graphs
, 2018 In this paper, we count the number of isomorphism classes of bipartite n-cyclic permutation graphs up to positive natural isomorphism and show that it is equal to the number of double cosets of the dihedral group D-n in the subgroup B-n of the symmetric ...

On Hypergraph and Graph Isomorphism with Bounded Color Classes ⋆
, 2008 . Using logspace counting classes we study the computational complexity of hypergraph and graph isomorphism where the vertex sets have bounded color classes for certain specific bounds.

On Uq (sl2)-actions on the Quantum Plane
Acta Polytechnica, 2010 To give the complete list of Uq (sl2)-actions of the quantum plane, we first obtain the structure of quantum plane automorphisms. Then we introduce some special symbolic matrices to classify the series of actions using the weights.

Conductors of fractional ideals in Burnside rings for cyclic p-groups and their zeta function
Revista IntegraciónThis study is part of the zeta function of the Burnside ring study. The main objective of this paper is to determine the conductors of all isomorphism classes of fractional ideals of finite index in Bp(Cp^n ) the Burnside ring for cyclic groups of order

Counting isomorphism classes of $\beta$-normal linear lambda terms
, 2015 5 pagesUnanticipated connections between different fragments of lambda calculus and different families of embedded graphs (a.k.a. "maps") motivate the problem of enumerating $\beta$-normal linear lambda terms.

On The Isomorphism Classes Of Transversals III
, 2011 Let $G$ be a finite group and $H$ a subgroup of $G$. Each left transversal (with identity) of $H$ in $G$ has a left loop (left quasigroup with identity) structure induced by the binary operation of $G$. We say two left transversals are isomorphic if they are isomorphic with respect to the induced left loop structures. In this paper, we develop a method

ISOMORPHISM CLASSES OF PICARD CURVES OVER FINITE FIELDS
, 2008 . In this paper we determine the number of isomorphism classes of Picard curves, i.e., superelliptic curves y 3 = f(x) of genus three, over finite fields of characteristic different from 3.
