Auslander Reiten Quiver of Nakayama Algebra type Dynkin Graph An Anwar, Faisal; Irawati, I.; Muchtadi-Alamsyah, Intan
Journal of Mathematical and Fundamental Sciences Vol 45, No 1 (2013)
Publisher : ITB Journal Publisher, LPPM ITB

Abstract

In this paper we will determine Auslander Reiten quiver of Nakayama algebra with quiver type Dynkin graph An for all natural number n â¥ 2. The AR-quiver is a visualization of module category of finite dimensional algebras. From the AR-quiver of an algebra A we may know all the isomorphism classes of indecomposable modules in mod A and the homomorphism between them. Once we get the general shape of the AR-quiver of this algebra, we will use it to compute a tilting module of this algebra.

Abstract

Given a large number of birds in the flock, we mathematically investigate the mechanism the birds move in a collective behavior. We assume that each bird is able to know its position and velocity of other birds within a radius of communication. Thus, to be able to fly in the flock, a bird has to adjust its position and velocity according to his neighbors. For this purpose, first of all, we analyze how the connectedness of the bird interaction network affects the cohesion of the stable bird flock. We further analyze a condition when the flock is vulnerable, which is mathematically indicated by means of the presence of an articulation point in bird communication network.
CHARACTERIZATION OF NAKAYAMA \$m\$-CLUSTER TILTED ALGEBRAS OF TYPE \$A_n\$ Faisal, Faisal; Muchtadi-Alamsyah, Intan
Journal of the Indonesian Mathematical Society Volume 22 Number 2 (October 2016)
Publisher : IndoMS

Abstract

Abstract. For any natural natural number m, the m-cluster tilted algebras are generalization of cluster tilted algebras. These algebras are defined as the endomorphism ofÂ certain objects in m-cluster category called m-cluster tilting objects. Finding such objectin the m-cluster category has become a combinatorial problem. In this article we charac-terize Nakayama m-cluster tilted algebras of type An by geometric description given byBaur and Marsh.DOI :Â http://dx.doi.org/10.22342/jims.22.2.213.93-130
Modul Herediter atas aljabar Lintasan Leavitt dari Graf Aâˆž Kariman, Delsi; Irawati, Irawati; Muchtadi-Alamsyah, Intan

Kode Siklis dari Sebuah Monomial Nopendri, Nopendri; Muchtadi-Alamsyah, Intan; Suprijanto, Djoko; Barra, Aleams
Jurnal Matematika Integratif Volume 15 No 1 (April 2019)

Abstract

Kode siklis merupakan salah satu topik riset paling aktif dalam teori koding karena memiliki banyak aplikasi pada sistem penyimpanan data dan komunikasi. Hal ini dikarenakan kode siklis memiliki algoritma encoding dan decoding yang efisien. Dalam makalah ini, dijelaskan tentang konstruksi kode siklis dari barisan yang dibangun oleh trace dari sebuah monomial atas lapangan hingga karakteristik dua. Beberapa contoh dari kode yang diperoleh ditampilkan pada makalah ini.
