Congruences for Taylor expansions of quantum modular forms [PDF]
, 2014 Recently, a beautiful paper of Andrews and Sellers has established linear congruences for the Fishburn numbers modulo an infinite set of primes. Since then, a number of authors have proven refined results, for example, extending all of these congruences ...

A Note on Congruences of Infinite Bounded Involution Lattices
Scientific Annals of Computer Science, 2021 We prove that an infinite (bounded) involution lattice and even pseudo-Kleene algebra can have any number of congruences between 2 and its number of elements or equalling its number of subsets, regardless of whether it has as many ideals as elements or ...

Random walks on semaphore codes and delay de Bruijn semigroups [PDF]
, 2015 We develop a new approach to random walks on de Bruijn graphs over the alphabet $A$ through right congruences on $A^k$, defined using the natural right action of $A^+$.

Variations of Andrews-Beck type congruences [PDF]
, 2020 We prove three variations of recent results due to Andrews on congruences for $NT(m,k,n)$, the total number of parts in the partitions of $n$ with rank congruent to $m$ modulo $k$.

Canonical forms for unitary congruence and *congruence [PDF]
Linear and Multilinear Algebra, 2009 We use methods of the general theory of congruence and *congruence for complex matrices--regularization and cosquares-to determine a unitary congruence canonical form (respectively, a unitary *congruence canonical form) for complex matrices A such that \bar{A}A (respectively, A^2) is normal.

Congruences and subdirect representations of graphs
Electronic Journal of Graph Theory and Applications, 2020 A basic tool in universal algebra is that of a congruence. It has been shown that congruences can be defined for graphs with properties similar to their universal algebraic counterparts.

S-Acts with Finitely Generated Universal Congruence [PDF]
Mathematics Interdisciplinary Research, 2022 Universal left congruences on semigroups were studied in “Y. Dandan, V. Gould, T. Quinn-Gregson and R. Zenab, Semigroups with finitely generated universal left congruence, Monat. Math. 190 (2019) 689−724”.

Congruences for 9-regular partitions modulo 3 [PDF]
, 2013 It is proved that the number of 9-regular partitions of n is divisible by 3 when n is congruent to 3 mod 4, and by 6 when n is congruent to 13 mod 16. An infinite family of congruences mod 3 holds in other progressions modulo powers of 4 and 5.

Discussiones Mathematicae - General Algebra and Applications, 2001 If \(\mathfrak{A}\) is an algebra then \(\text{Con}({\mathfrak A})\) is the set of all congruences on \({\mathfrak A}\). If \(\Phi\in \text{Con}({\mathfrak A})\), \(x\in{\mathfrak A}\), then \([x]\Phi=\{t\in{\mathfrak A}\mid (x;t)\in\Phi\}\). If \(M\subseteq{\mathfrak A}\) then \(\Theta(M)\) is the least congruence on \({\mathfrak A}\) containing the ...

International Journal of Mathematics, 2013 A new category of algebro-geometric objects is defined which contains the category of monoid schemes, or schemes over 𝔽1, and the category of Grothendieck schemes as subcategories.
