i would also not like to ask, but if not ask, what should i do?

i mean the term which contain the a variable which power is the highest among all the terms

in above case should be y^2

however after i search manual no function result in this

product means a product term only has product, for example a*b, a*b*c, a*b*c*d ,etc

if there is a framework to let me plug in integration rules in it, then it is very convenient

it do not have q-Laplace, i need inverse q-Laplace, it has q for q-hypergoemetric

why look LREtools?

actually i need q integration, how to implement a new kind of integration like maple do such as

i use continuous fourier transform continous to discrete, failed

i := 2;

disnetwork := int(exp(-I*s*u)*contnetwork, s=-infinity..infinity);

ztrans(disnetwork, s, z);

then i use dynamic system's function, can not convert because not a system object

restart;
with(inttrans):
with(SumTools):
with(DynamicSystems):
network := sqrt(2*p)*((s-p)^(i-1))/((s+p)^i):
sys := subs(i=2, network):
disnetwork := ToDiscrete(sys, 1, method = forward);
disnetwork := ToDiscrete(sys, 1, method = backward);
disnetwork := ToDiscrete(sys, 1, method = bilinear);

then i try matlab, it can convert but not the expected

syms s p;
contnetwork = sqrt(2*p)*((s-p)^(i-1))/((s+p)^i);
c2d(contnetwork,0.1,'foh')
c2d(contnetwork,0.1,'imp')

## when try to reverse find back alpha and ...

when try to reverse find back alpha and x from existing equations

x and alpha are very complex

solve({sqrt(2*p)*exp(-p*t) = exp(x)*(x^(-alpha))/0!*exp(-x)*(x^(0+alpha)), sqrt(2*p)*(-2*p*t+1)*exp(-p*t) = exp(x)*(x^(-alpha))/1!*diff(exp(-x)*(x^(1+alpha)), x\$1)},{alpha,x});

i still suspect this rodrigue formula is the source

here it is,

once you got it, tell me, i will delete it after you got it.
