If I can name 3.3 kilo-ohm resistor as 3k3, then can I name 4.7 micro farad capacitor as 4μ7 in my schematic notations?

It means that there are multiple pins on the device to handle high current or for lower inductance. They are wired together at the same potential.
Omitting the supply rails and decoupling capacitors is a common shorthand in circuit diagrams. It's admissible, when supply rails are not important for the discussion.
0.001 μF in the original post is not a decoupling capacitor. It's a compensation capacitor between pins 1 and 8 of the CA3130 OpAmp.
fig.8 on p.9 in the datasheet. Decoupling capacitors in this schematic are 0.01 μF, compensation capacitor in this schematic is 56 pF.
Best Answer
Yes, this is very common.
The reason to use this kind of notation is, that it is less error prone. Because you can easily miss the decimal separator if the quality of the a printout (schematic on paper, component labeling etc.) is not optimal.
