Let \((a)_{n}=a(a+1)\cdots (a+n-1)\) be the Pochhammer symbol. Recently, Jana and Kalita proved the following two supercongruences:

$$\begin{aligned} \sum _{k=0}^{(p-1)/3} (6k+1)\frac{(\frac{1}{3})_k^4 (2k)!}{k!^4 (\frac{2}{3})_{2k}}&\equiv p\pmod {p^3}\quad \text {for primes }\,{ p\equiv 1\pmod {3},} \\ \sum _{k=0}^{(p+1)/3} (6k-1)\frac{(-\frac{1}{3})_k^4 (2k)!}{k!^4 (-\frac{2}{3})_{2k}}&\equiv p\pmod {p^3} \quad \text {for primes }\,{p\equiv 2\pmod {3},} \end{aligned}$$

which were originally conjectured by the second author and Schlosser. In this note, employing the creative microscoping method introduced by the second author and Zudilin, we give curious q-analogues of the above two supercongruences.

好奇的q-两个超模的模数,素数的三次方

\((a)_ {n} = a(a + 1)\ cdots(a + n-1)\)为Pochhammer符号。最近,Jana和Kalita证明了以下两个超同余:

$$ \ begin {aligned} \ sum _ {k = 0} ^ {(p-1)/ 3}(6k + 1)\ frac {(\ frac {1} {3})_ k ^ 4(2k)! } {k!^ 4(\ frac {2} {3})_ {2k}}&\ equiv p \ pmod {p ^ 3} \ quad \ text {for primes} \,{p \ equiv 1 \ pmod { 3},} \\ \ sum _ {k = 0} ^ {(p + 1)/ 3}(6k-1)\ frac {(-\ frac {1} {3})_ k ^ 4(2k)! } {k!^ 4(-\ frac {2} {3})_ {2k}}&\ equiv p \ pmod {p ^ 3} \ quad \ text {for primes} \,{p \ equiv 2 \ pmod {3},} \ end {aligned} $$

最初由第二作者和Schlosser推测。在本说明中,采用第二作者和Zudilin引入的创造性微观范围分析方法,我们给出了上述两个超同余的奇异q-模拟。
