In terms of the creative microscoping method, El Bachraoui's lemmas, and the Chinese remainder theorem for coprime polynomials, we establish some q-supercongruences for double and triple basic hypergeometric series. Several related conjectures are also proposed for further research. [ABSTRACT FROM AUTHOR]

Let $ \beta (z) $ β (z) be the Dirichlet beta function. Series for $ \beta (4) $ β (4) are very rare in the historical development of mathematics. With the help of the operator method and a transformation formula for hypergeometric series, we prove a surprising conjectural series of Z.-W Sun for the mathematical constant $ \beta (4) $ β (4). Furthermore, we find five new series for the same constant in this paper. [ABSTRACT FROM AUTHOR]

We derive a q-supercongruence modulo the third power of a cyclotomic polynomial with the help of Guo and Zudilin's method of creative microscoping ['A q-microscope for supercongruences', Adv. Math.346 (2019), 329–358] and the q-Dixon formula. As consequences, we give several supercongruences including $$ \begin{align*}\sum_{k=0}^{(p-2)/3}\frac{(\frac{2}{3})_k^3}{(1)_k^3}\equiv\frac{p}{2}\frac{(1)_{(p-2)/3}}{(\frac{4}{3})_{(p-2)/3}}\pmod{p^3},\end{align*} $$ where p is a prime with $p\equiv 5\pmod {6}$.

In terms of the q-Saalschütz identity, the creative microscoping method recently introduced by Guo and Zudilin [Adv. Math. 346 (2019), pp. 329–358], and the Chinese remainder theorem for coprime polynomials, we establish some q-supercongruences modulo the third power of a cyclotomic polynomial. In particular, we give a q-analogue of a formula due to Long and Ramakrishna [Adv. Math. 290 (2016), pp. 773–808]. [ABSTRACT FROM AUTHOR]

q -Supercongruences modulo the fifth and sixth powers of a cyclotomic polynomial are very rare in the literature. In this paper, we establish some q -supercongruences modulo the fifth and sixth powers of a cyclotomic polynomial in terms of Jackson's ϕ 7 8 summation, Watson's ϕ 7 8 transformation, the creative microscoping method recently introduced by Guo and Zudilin, and the Chinese remainder theorem for coprime polynomials. More concretely, we give a q -analogue of a nice formula due to Long and Ramakrishna [Adv. Math. 290 (2016), 773–808] and two q -supercongruences involving double series. [ABSTRACT FROM AUTHOR]

In 1981, Andrews gave a four-variable generalization of Ramanujan's 1 ψ 1 summation formula. We establish a six-variable generalization of Andrews' identity according to the transformation formula for two 8 ϕ 7 series and Bailey's transformation formula for three 8 ϕ 7 series. Then, it is used to find a six-variable generalization of Ramanujan's reciprocity theorem, which is different from Liu's formula. We derive the generalizations of Bailey's two 3 ψ 3 summation formulas in terms of two limiting relations and Bailey's another transformation formula for three 8 ϕ 7 series. Based on the two limiting relations, some different results involving bilateral basic hypergeometric series are also deduced from the Guo–Schlosser transformation formula and other two transformation formulas.

Recently, Wang and Ma proposed a conjecture, embedding the Andrews–Warnaar partial theta function identity in an infinite family of such identities. In this paper we use q-series methods to give a proof of the Wang–Ma conjecture. We also present a result which may be regarded as the inverse of the Wang–Ma conjecture. [ABSTRACT FROM AUTHOR]

In 2017, He (2017) [9] established two supercongruences on truncated hypergeometric series and further proposed two related conjectures. Subsequently, Liu (2017) [11] extended He's formulas and confirmed the second conjecture. However, the first conjecture is still open up to now. With the help of the creative microscoping method and the Chinese remainder theorem for coprime polynomials, we derive several q -supercongruences modulo the fourth and fifth powers of a cyclotomic polynomial from Gasper and Rahman's summation formula for basic hypergeometric series. As conclusions, He's first conjecture is confirmed and a more general form of He's second conjecture is proved. [ABSTRACT FROM AUTHOR]

Meanwhile, two series for 1/π with three free parameters are also derived in the same way. [ABSTRACT FROM AUTHOR]

With the help of the creative microscoping method recently introduced by Guo and Zudilin and the Chinese remainder theorem for coprime polynomials, we establish a q -supercongruence with two parameters modulo [ n ] Φ n (q) 3. Here [ n ] = (1 − q n) / (1 − q) and Φ n (q) is the n -th cyclotomic polynomial in q. In particular, we confirm a recent conjecture of Guo and give a complete q -analogue of Long's supercongruence. The latter is also a generalization of a recent q -supercongruence obtained by Guo and Schlosser. [ABSTRACT FROM AUTHOR]

The embryonic stem cell (ESC) has the capacity to self-renew and maintain pluripotent, while continuously offering a source of various differentiated cell types. The fate decision process of remaining in the ground state or transiting to a differentiated state can be read out by the regulatory network of key transcription factors (TFs). However, its underlying mechanism remains to be fully elucidated. In this paper, we tackle this problem by proposing a novel cellular differentiation model for mouse embryonic stem cell (MESC) dynamics regulation: MESC-DRM. We employ nonlinear least-squares algorithm to infer model parameters by using benchmark datasets, construct a potential function by exploiting multivariate Gaussian distributions, and project the potential landscape into a 3D space to validate and replicate the stable cell states observed in experiments. The traditional cell landscape modeling techniques rely on the potential function visualization to decide the stable states of cells. But the visualization will be almost impossible when the dimensionality of the potential function is greater than 3. We handle the challenge by innovatively employing a Lyapunov method to resolve it through a more straightforward analytical approach. It also provides a more rigorous and robust way for accurate cell fate decision. The study not only validates the previous experimental results but also provides an insightful guide for cell fate decision besides inspiring future study on this topic.
