Matrix product state representations [PDF]
This work gives a detailed investigation of matrix product state (MPS) representations for pure multipartite quantum states. We determine the freedom in representations with and without translation symmetry, derive respective canonical forms and provide efficient methods for obtaining them. Results on frustration free Hamiltonians and the generation of

The Cyclic Decomposition of cf(Q_28×C_p)/ R ̅(Q_28×C_p)
In this paper, we propose the cyclic decomposition of the factor group cf(Q_28×C_p),Z)/R ̅(Q_28×C_p ), and the group cf(Q_28×C_p ) is Z-valued class functions of the direct product group (Q_28×C_p ) under the operation of addition, and R(Q_28×C_p )is ...

Memory capacity of recurrent neural networks with matrix representation
It is well known that canonical recurrent neural networks (RNNs) face limitations in learning long-term dependencies, which have been addressed by memory structures in long short-term memory (LSTM) networks. Neural Turing machines (NTMs) are a variant of

Generation matrix: An embeddable matrix representation for hierarchical trees
Starting from the local structures to study hierarchical trees is a common research method. However, the cumbersome analysis and description make the naive method challenging to adapt to the increasingly complex hierarchical tree problems. To improve the efficiency of hierarchical tree research, we propose an embeddable matrix representation for ...

A graph-based approach for detection degenerate structures in multi-planet gear trains
A locked chain is an immovable sub-chain within a kinematic chain. The detection of immovable sub-chains is a critical step in the structural synthesis of planetary gear trains (PGTs).

The Cyclic Decomposition of cf(Q2q×C10)/ R ̅ (Q29×C10)
In this paper, we propose the cyclic decomposition of the factor group cf(Q2q×C10)‚Z)/R ̅(Q2q×C10 ), and the group cf(Q2q×C10‚Z) is Z-valued class functions of the direct product group ((Q14×C10)) under the operation of addition, and R((Q14×C10)) is the

Triangular Matrix Representations
A ring \(R\) is said to have a GTMR (reviewer's abbreviation for ``generalised triangular matrix representation'') if there is a positive integer \(n\) such that \(R\) is isomorphic to the ring of all \(n\times n\) upper triangular matrices with \(i\)-th diagonal entry in some ring \(R_i\) and with above-diagonal \((i,j)\)-entry in an \(R_i\)-\(R_j ...
